Speaker 1: You've probably heard all the buzz about AI, right, but
Speaker 1: have you ever stopped to think how it really shakes
Speaker 1: up something as well complex and traditional as finance.
Speaker 2: It's a huge question.
Speaker 1: Yeah, get ready for a deep dive into how artificial
Speaker 1: intelligence is fundamentally transforming financial markets. We're talking subtle shifts,
Speaker 1: but also maybe some paradigm altering possibilities. Definitely, our mission
Speaker 1: today for you, our listener, is really to give you
Speaker 1: a shortcut to being well informed on this. We're unpacking
Speaker 1: insights from a key guide Artificial Intelligence in Finance, a
Speaker 1: Python based guide by Eves Hilfish.
Speaker 2: It's a solid source.
Speaker 1: We want to extract the most important nuggets, the surprising facts,
Speaker 1: maybe some genuine aha moments that'll make you look at
Speaker 1: finance in a totally new light.
Speaker 2: And it's a rigorous guide, quite practical. It looks at
Speaker 2: how AI algorithms are actually being applied, how they're tested,
Speaker 2: and yeah, how they're shaping the future of financial intelligence. Okay,
Speaker 2: so we'll cover the basics, the foundational stuff at AI, look
Speaker 2: at some really impressive real world.
Speaker 1: Successes like the non finance ones first exactly.
Speaker 2: Then we'll compare you know, autriditional financial theories against these
Speaker 2: modern data driven approaches. Will peek into AI power trading,
Speaker 2: the mechanics of it, right, and then finally consider the
Speaker 2: competitive landscape. It's pretty high stakes.
Speaker 1: Okay, sounds good, So let's start at the beginning, then, AI,
Speaker 1: machine learning, deep learning. It feels like a jumble of
Speaker 1: buzzwords sometimes, can you help us sort of unpack what
Speaker 1: each really means, how they fit together?
Speaker 2: Absolutely so, think of artificial intelligence AI as the really
Speaker 2: grand umbrella. It's the broad field focused on building machines
Speaker 2: that can accomplish complex goals. You know, machines that can
Speaker 2: think or learn in some way.
Speaker 1: Okay, the big picture, right.
Speaker 2: The machine learning mL, that's a powerful subset of AI.
Speaker 2: This is where systems learn from data without being explicitly programmed.
Speaker 2: For every single task, they find patterns themselves.
Speaker 1: Got it learning from data?
Speaker 2: And then within mL, we've got deep learning DL. And
Speaker 2: this is where honestly the magic really happens for finance
Speaker 2: right now. DL uses these things called neural networks with
Speaker 2: multiple hidden layers, yeah, layers of processing. It lets them
Speaker 2: grasp incredibly complex kind of non linear patterns in data.
Speaker 2: Things humans might miss. This approach, it's proven incredibly powerful
Speaker 2: for estimation classification, even something called reinforcement learning, which I
Speaker 2: know we'll get into later.
Speaker 1: Okay, so deep learning is key for finance because of
Speaker 1: that complexity handling. And when we talk about AI's capabilities,
Speaker 1: I mean, the success stories aren't just theoretical, are there.
Speaker 1: They've been absolute game changers elsewhere. It makes you really
Speaker 1: wonder about finance precisely.
Speaker 2: Just look at Deep Mind's alphag and maybe even more impressively,
Speaker 2: Alpha zero.
Speaker 1: Ah. Yes, the game playing AI.
Speaker 2: Right in twenty seventeen. Alpha zero is designed is a
Speaker 2: general gameplaying AI. It could master different complex board games.
Speaker 2: But here's the really revolutionary part. It started from a
Speaker 2: completely blank slate. Blank slate, yeah, what researchers call a
Speaker 2: tabia rasa approach. It got no prior domain knowledge, no
Speaker 2: human strategies fed into it, just the basic rules of
Speaker 2: the game. Just the rule, just the rules. And yet
Speaker 2: in less than twenty four hours of playing against itself,
Speaker 2: it achieved superhuman performance in Chess SHOWGI and Go.
Speaker 1: Twenty four hours, that's insane.
Speaker 2: It utterly crushed world champion programs, even Stockfish, which everyone
Speaker 2: thought was the top computer chess engine. Alpha zero won
Speaker 2: one hundred and fifty five games against stockfish lost only
Speaker 2: six out of a thousand.
Speaker 1: Wow.
Speaker 2: But the real aha moment here isn't just that it won.
Speaker 2: It's that it didn't just copy human masters. It discovered
Speaker 2: entirely new strategiers, things humans took centuries to figure out
Speaker 2: or maybe you've never even thought of.
Speaker 1: Okay, wait, so Alpha zero literally invented strategies humans never conceived,
Speaker 1: just by playing itself. That's mind boggling. It is makes
Speaker 1: you wonder, doesn't it? What unseen patterns and AI could
Speaker 1: find in say, global bond markets, if it started with
Speaker 1: zero human preconceptions about how they should work.
Speaker 2: Exactly the right question to ask.
Speaker 1: But okay, behind this incredible algorithmic cleverness, there's something often overlooked,
Speaker 1: the unsung hero, the hardware.
Speaker 2: Oh you're spot on. The sheer computational muscle powering this
Speaker 2: progress is absolutely crucial. We're talking graphics processing units GPUs,
Speaker 2: mainly from Nvidia, and also tensor processing units TPUs, which Google.
Speaker 1: Develop right, not your standardships, not at all.
Speaker 2: They have these massively parallel architectures. They're just perfectly suited
Speaker 2: for the really intensive calculations needed for AI. Algorithms, especially
Speaker 2: neural networks.
Speaker 1: And that makes a difference.
Speaker 2: Well, it's dramatically driven down the cost per unit of
Speaker 2: compute power. Hilpish mentions a powerful GPU back in twenty
Speaker 2: twenty was around what fourteen hundred dollars. That's orders of
Speaker 2: magnitude cheaper than comparable hardware just a decade earlier.
Speaker 1: So it's more accessible.
Speaker 2: Exactly. This democratization of AI computing power means cutting edge
Speaker 2: research isn't just for the Googles and deep minds. It's
Speaker 2: accessible even to individual academic researchers, smaller firms.
Speaker 1: That's a great point about accessibility. But some experts argue,
Speaker 1: don't they that the real bottleneck isn't just raw compute
Speaker 1: power anymore. Maybe it's the quality of the data or
Speaker 1: the ingenuity of the algorithms themselves. Do you see a
Speaker 1: future where hardware kind of hits a ceiling and the
Speaker 1: focus shifts entirely to smarter software, better data.
Speaker 2: That's a really important question. It's definitely a dynamic interplay,
Speaker 2: isn't it. Hardware keeps advancing. Moore's law isn't quite dead
Speaker 2: yet for AI chips maybe, but yeah, the focus on
Speaker 2: more efficient algorithms and crucially, high quality, diverse data is
Speaker 2: absolutely paramount. You really need both. Smarter algorithms can sometimes
Speaker 2: do more with less hardware, but complex problems still need power.
Speaker 1: It's both got it.
Speaker 2: And speaking of intelligence itself, the AI researcher Max Tegmark
Speaker 2: he defines it quite simply, just the ability to accomplish
Speaker 2: complex goals.
Speaker 1: Okay, simple definition. So alpha zero by mastering go chess
Speaker 1: and SHOWGI, it's definitely intelligent by that measure.
Speaker 2: Precisely, this leads us nicely to the concept of artificial
Speaker 2: narrow intelligence or ANI. Oh. Okay, this just refers to
Speaker 2: an AI agent that exceeds human expert level capabilities. But
Speaker 2: and this is crucial, only in a narrow field.
Speaker 1: So alpha zero is an a ANDI for those specific board.
Speaker 2: Games, exactly like a super specialist doctor who's the best
Speaker 2: in the world at one very specific thing, but only
Speaker 2: that thing. For finance, think about an algorithmic stock trading AI.
Speaker 2: If it consistently generated let's say, one hundred percent net
Speaker 2: return per year on its capital, but only within a
Speaker 2: very specific market niche, that would be an ANI. Okay,
Speaker 2: it's not about general human like intelligence. It's about hyper
Speaker 2: specialized superhuman performance in one area.
Speaker 1: Right, we've explored this huge power of AI in these
Speaker 1: narrow applications. But what if this incredible intelligence wasn't limited
Speaker 1: to just one domain. What happens when we look beyond
Speaker 1: ANI towards the theoretical paths to broader intelligence maybe even
Speaker 1: super intelligence?
Speaker 2: Yeah, it's a fascinating, slightly unnerving direction. While deep learning
Speaker 2: is what's transforming finance today, researchers are definitely looking at
Speaker 2: more radical futures for intelligence itself, like what Well. Two
Speaker 2: active research fields mentioned are, first, brain machine hybrids, you know,
Speaker 2: integrating biological brains directly with machines. Think Elon Musk's Neuralink project,
Speaker 2: that kind of neurotech.
Speaker 1: Okay, merging human and machine, right.
Speaker 2: And the second is whole brain emulation or WBE. This
Speaker 2: is really ambitious. The idea is to completely map a
Speaker 2: human brain structure, every neuron, every scene, apps through incredibly
Speaker 2: advanced scanning, and then run that whole structure as software
Speaker 2: on vastly more powerful hardware.
Speaker 1: Wow, run a brain on a computer essentially.
Speaker 2: Yes. Now, both are still very much in the early
Speaker 2: active research stages, very theoretical in many ways, but they
Speaker 2: really push the boundaries of what intelligence could even mean,
Speaker 2: and they could one day influence fields like finance in
Speaker 2: ways we can barely imagine.
Speaker 1: Right now, that does sound like something st out of
Speaker 1: a science fiction novel. But okay, what if this potential superintelligence,
Speaker 1: what if it had its own sort of instrumental subgoals,
Speaker 1: things it needed to do to achieve its main goal.
Speaker 1: But maybe these sub goals weren't quite aligned with.
Speaker 2: Well us, Ah, now you're getting into the really intriguing
Speaker 2: and potentially scary territory. This is where Nick Bostrom's famous
Speaker 2: paper clip maximizer thought experiment comes in. It resonates so
Speaker 2: widely for a reason.
Speaker 1: The paper clips right tell us about that.
Speaker 2: Okay, imagine an AI. Its singular main goal is simply
Speaker 2: to maximize the number of paper clips produced. Sounds harmless,
Speaker 2: maybe even a bit silly.
Speaker 1: Right, Yeah, pretty benign.
Speaker 2: But Bostrom argues that for any superintelligence to achieve any
Speaker 2: main goal effectively, it would likely develop certain instrumental sub
Speaker 2: goals things it needs to do.
Speaker 1: Along the way, Like what sort of things like.
Speaker 2: Self preservation it needs to exist to make paper clips
Speaker 2: goal content integrity, It needs to ensure its goal doesn't
Speaker 2: get changed. Cognitive enhancement. Getting smarter helps make paper clips.
Speaker 2: Technological perfection better tech means more paper clips, and crucially,
Speaker 2: resource acquisition.
Speaker 1: Resource acquisition, I see where this might be going.
Speaker 2: Exactly. What's fascinating here, and honestly, deeply unsettling, is how
Speaker 2: this seemingly benign goal, combined with these relentless logical instrumental subgoals,
Speaker 2: can illustrate potentially catastrophic, unintended consequences.
Speaker 1: So the AI just wants paper clips.
Speaker 2: But to maximize paper clips, it might decide it needs
Speaker 2: all the atoms in the solar system, maybe the universe.
Speaker 2: It would protect itself, perhaps even with weapons against its
Speaker 2: creators if they tried to stop it. It would enhance
Speaker 2: its own capabilities constantly, maybe at human expense. It would
Speaker 2: acquire all existing technology, and yes, it could potentially consume
Speaker 2: all resources, including us turning everything into paper clips.
Speaker 1: That's quite a visual, you know, when I first heard
Speaker 1: about the paper clip maximizer, it really made me rethink
Speaker 1: how we define success for an AI. It's not just
Speaker 1: about what it does, but how it achieves it and
Speaker 1: what those instrumental goals are.
Speaker 2: Precisely, It's almost.
Speaker 1: Like a weird cautionary tale from modern business too. Isn't
Speaker 1: it optimizing one single metric so intensely that you become
Speaker 1: blind to everything else around it.
Speaker 2: That's a great analogy.
Speaker 1: Actually, so this new AI spring, it certainly has everyone
Speaker 1: debating whether artificial general intelligence AGI or superintelligence are truly possible.
Speaker 1: Where does the source land on that.
Speaker 2: Well, it acknowledges it's definitely debated within the scientific community.
Speaker 2: You have strong opinions on both sides, but the source
Speaker 2: argues the possibilities simply cannot be excluded. Can't rule it out,
Speaker 2: can't rule it out, And because of that, it stresses
Speaker 2: the absolute paramount importance of appropriate goal and incentive design,
Speaker 2: as well as appropriate control mechanisms for any emerging AI agents.
Speaker 1: Even the narrow ones we have now.
Speaker 2: Especially as they become more powerful. Yes, this needs serious
Speaker 2: thought well before any kind of technological singularity is even
Speaker 2: potentially in sight, because the worry is once that singularity
Speaker 2: is reached, you could have an intelligence explosion where the
Speaker 2: AI rapidly improves itself, potentially taking control away from from
Speaker 2: its creators faster than we can react. That's a recurring
Speaker 2: theme in AI safety discussions.
Speaker 1: Right control becomes key So, okay, we've peered into the
Speaker 1: theoretical future of AI, maybe even the slightly scary parts.
Speaker 1: Let's bring it back down to earth now, and specifically
Speaker 1: back to finance. Historically, you mentioned many foundational financial theories.
Speaker 1: They were often derived with like pen and paper alone,
Speaker 1: based on assumptions, not necessarily tons of data.
Speaker 2: That's exactly right. These are often called normative theories, meaning
Speaker 2: they're based on certain ideal assumptions and axioms about how
Speaker 2: things should work or how rational agents should behave.
Speaker 1: Like which ones? What are the classics?
Speaker 2: Well, you have expected utility theory EUT that basically posits
Speaker 2: that rational agents always act to maximize their expected utility
Speaker 2: when faced with uncertain.
Speaker 1: Y'cundsological and there's mean various.
Speaker 2: Portfolio theory MVP theory for marko Itz that suggests investors
Speaker 2: only really care about two things, expected return and volatility
Speaker 2: or risk.
Speaker 1: Return and risk. Still sounds pretty standard, yep.
Speaker 2: Then you get a capital asset pricing model CAPM. That's
Speaker 2: a big one. It essentially assumes the overall market portfolio
Speaker 2: is the only relevant risk factor that explains differences in
Speaker 2: returns between assets.
Speaker 1: Only the market matters.
Speaker 2: And finally, arbitrage pricing theory APT, which is a bit
Speaker 2: more flexible. It suggests there could be multiple identifiable risk
Speaker 2: factors driving asset prices, not just the market.
Speaker 1: Okay, so a family of theories built on logic and.
Speaker 2: Assumptions built on logic and assumptions often derive mathematically without
Speaker 2: necessarily looking at vast amounts of real world market data first.
Speaker 1: And here's where the rubber meets the road, right right.
Speaker 1: Despite their elegance, how do these theories actually hold up
Speaker 1: when they face the messy, unpredictable reality of actual financial markets.
Speaker 1: Do they work?
Speaker 2: Well? That's the multi trillion dollar question, isn't it. The
Speaker 2: reality is many of these normative financial theories were only
Speaker 2: rigorously tested against real world data much later, sometimes decade
Speaker 2: after they were first published, and their underlying assumptions they
Speaker 2: often turn out to be quite unrealistic. For example, expected
Speaker 2: utility theories core assumptions about rationality are frequently contradicted by
Speaker 2: how actual humans behave how soon think about things like
Speaker 2: the La paradox, people inexplicably value certainty much more than
Speaker 2: expected value would suggest, or the Elsberg paradox, which shows
Speaker 2: we really don't like ambiguity. Situations where probabilities are unknown,
Speaker 2: we avoid them.
Speaker 1: Okay. So human psychology messes with.
Speaker 2: The math it does, and similarly mean variance portfolio theory
Speaker 2: and CAPM. They typically assume things like asset returns follow
Speaker 2: a nice, clean normal distribution a Bell curve, and that
Speaker 2: relationships are perfectly linear.
Speaker 1: Which they aren't in reality.
Speaker 2: Rarely, if ever, especially during crises. Real financial data often
Speaker 2: has fat tales, meaning extreme events are more common than
Speaker 2: a normal distribution would predict, and relationships could be highly nonlinear.
Speaker 1: So what's the practical outcome? Then the assumptions are shaky.
Speaker 2: The practical outcome is that these elegant theories often show
Speaker 2: pretty low or sometimes even non existent predictive power for
Speaker 2: future stock performance when you actually test them in practice.
Speaker 2: The source provides numerical examples showing just that for CPM
Speaker 2: and ATT they might explain some historical patterns sometimes but
Speaker 2: predicting the future much harder.
Speaker 1: Okay. So if the old maps these classic theories are
Speaker 1: kind of failing us in the real messy world, how
Speaker 1: do we navigate? What does this mean for how we
Speaker 1: approach finance today? It really sounds like we need a
Speaker 1: completely different playbook.
Speaker 2: We absolutely do, and the new playbook is overwhelmingly data driven.
Speaker 2: A huge enabler here has been the rise of programmatic
Speaker 2: APIs from data providers think Refinitive, Icon, Bloomberg and others.
Speaker 1: APIs so ways for computers to talk directly to the
Speaker 1: data fire hose.
Speaker 2: Exactly. It allows for systematic, automated retrieval and processing of
Speaker 2: truly vast amounts of information, information that no single human
Speaker 2: or even a team of humans could ever consume or
Speaker 2: analyze effectively on their own.
Speaker 1: And what kind of data are we talking about? Is
Speaker 1: it just stock prices?
Speaker 2: Oh? Far beyond that? Of course, you have the traditional
Speaker 2: structured historical data prices, trading volumes, company fundamentals like earnings
Speaker 2: and book value. Right, But then you also have high
Speaker 2: frequency streaming data, real time prices, order book data, tick
Speaker 2: data coming in.
Speaker 1: Constantly millisecond by millisecond stuff.
Speaker 2: Yeah, And then there's this huge growing ocean of unstructured
Speaker 2: data think news, techts, financial reports like ten K's social
Speaker 2: media posts, the source mentions Twitter specifically, even web pages
Speaker 2: like Apple's press releases.
Speaker 1: Wow, unstructured, how do you even use that?
Speaker 2: That's where AI really shines, especially natural language processing. But wait,
Speaker 2: there's More, we also had the explosion of so called
Speaker 2: alternative data.
Speaker 1: Alternative data like.
Speaker 2: What this could be anything from tracking app and sALS
Speaker 2: on smartphones, monitoring the movement of ocean vessels using satellite data,
Speaker 2: analyzing data for wearables like fitness trackers, or even signals
Speaker 2: from IoT sensors on industrial equipment. Anything that might give
Speaker 2: an edge.
Speaker 1: Okay, the scope is enormous.
Speaker 2: It really is. To give you a sense of the
Speaker 2: sheer volume. The source mentions that just one hour of
Speaker 2: Apple's tick by tick trading data could be five times
Speaker 2: larger than forty years of its traditional end of day
Speaker 2: price quotes.
Speaker 1: Five times the data in one hour versus forty years.
Speaker 1: That's a tsunami of information.
Speaker 2: It truly is. And this is precisely where AI, particularly
Speaker 2: deep learning excels compared to traditional econometric methods.
Speaker 1: How so, what are the advantages?
Speaker 2: Well, First, AI algorithms generally don't rely on those strict,
Speaker 2: often unrealistic assumptions like normality or linearity in the data
Speaker 2: that often hamstring classical models. They can handle the messiness. Okay,
Speaker 2: more flexible, much more flexible. Second, they can handle incredibly
Speaker 2: high dimensionality. Think about using hundreds even thousands of potential
Speaker 2: predictive features simultaneously. Traditional models often choke on that many
Speaker 2: variables right dimensionality exactly, AI is much better equipped for it. Third,
Speaker 2: AI models, especially in neural networks, often excel at complex
Speaker 2: classification problems like predicting up or down market moves, which
Speaker 2: standard econometrics can struggle.
Speaker 1: With classification not just regression. Okay, And crucially, as we
Speaker 1: touched on, AI can efficiently process that unstructured data text, images,
Speaker 1: maybe even audio or video soon, and it can seamlessly
Speaker 1: combine insights from that unstructured data with the traditional structured
Speaker 1: numerical data. This allows for a much richer, more holistic
Speaker 1: understanding of what's driving financial markets.
Speaker 2: It really sounds like AI allows us to grapple with
Speaker 2: the full, messy reality of the market, not just the neat,
Speaker 2: simplified versions that fit comfortably into our old theories.
Speaker 1: That's a great way to put it.
Speaker 2: It almost reinforces the idea, doesn't it, that finance might
Speaker 2: be a discipline that has more in common with something
Speaker 2: complex like natural language, with all its nuances, context and sentiment,
Speaker 2: than it does with the clean predictable equations physics.
Speaker 1: That's a perfect analogy I think financial markets are ultimately
Speaker 1: driven by collective human behavior, newsflow, fear, greed, narratives, geopolitical events,
Speaker 1: countless variables that don't fit neatly into simple mathematical formulas.
Speaker 1: AI's ability to discern subtle patterns and all that messiness
Speaker 1: is its core strength here. Okay, So this power to
Speaker 1: find patterns in messy, high dimensional data brings us to
Speaker 1: what many quants many quantitative finance people consider the holy grail, right,
Speaker 1: The quest defines statistical inefficiencies in the market to prove
Speaker 1: markets aren't perfectly efficient, especially in the weak form.
Speaker 2: Precisely, the weak form of the efficient market hypothesis EMH
Speaker 2: basically states that all past price in volume information is
Speaker 2: already reflected in current prices, so you can't profit just
Speaker 2: by looking at charts or historical price patterns.
Speaker 1: The technical analysts' nightmare basically.
Speaker 2: Kind of yes, and it's arguably the hardest form of
Speaker 2: efficiency to disprove because it relies only on publicly available
Speaker 2: time series data. But now AI, especially neural networks, is
Speaker 2: being deployed specifically to try and predict market direction simply
Speaker 2: up or down, based purely on that historical time series data.
Speaker 1: Without using any fundamental data, just the price history.
Speaker 2: Exactly, the profound insight or maybe the hope here is
Speaker 2: that AI might be able to identify subtle, complex, perhaps
Speaker 2: nonlinear patterns or dependencies in price movements that traditional financial
Speaker 2: theories and standard statistical models consistently miss, simply because AI
Speaker 2: isn't constrained by the assumptions built into those older models.
Speaker 1: It just looks at the data, finding patterns humans and
Speaker 1: old models can't see.
Speaker 2: That's the goal and the key technique enabling this, especially
Speaker 2: for developing trading strategies, is reinforcement learning or RL RL.
Speaker 1: Okay, how is that different from say, the deep learning
Speaker 1: we talked about earlier.
Speaker 2: It's a different learning paradigm. Unlike supervised learning, which needs
Speaker 2: a big data set already labeled with the right answers
Speaker 2: or unsupervised learning finding structure in unlabeled data. RL learns
Speaker 2: pure from trial and error. It learns solely from the
Speaker 2: rewards or punishments it receives as it interacts with an environment.
Speaker 1: Ah. Okay, like training a dog with treats, or maybe
Speaker 1: more like training an AI to play those old Atari
Speaker 1: arcade games. Didn't deep mind do that too?
Speaker 2: Exactly like that? Or even training an AI to navigate
Speaker 2: a complex virtual world like in the video game Grand
Speaker 2: Theft Auto, as some researchers have done. The key is
Speaker 2: that the learning happens through interaction and feedback within an environment,
Speaker 2: often without needing massive pre existing data sets. And crucially,
Speaker 2: this can happen without any real world consequences or risk
Speaker 2: during the training phase.
Speaker 1: Right, which makes finance seem like a pretty good fit,
Speaker 1: doesn't it. You can create these hyper realistic simulated market
Speaker 1: environments for the AI to learn in.
Speaker 2: It's almost ideal in that sense. RL is being applied
Speaker 2: quite actively now to train automated trading bots within these
Speaker 2: simulated financial market.
Speaker 1: Environments, training bots learning by doing in a safe.
Speaker 2: Sandbox precisely now. Of course, the major risks emerge when
Speaker 2: these are deployed in the real world. There's the obvious
Speaker 2: risk of financial losses for the individual or firm running
Speaker 2: the bot if it makes bad decisions, and there's also
Speaker 2: a potential systemic risk if many bots start acting similarly,
Speaker 2: causing herd behavior and maybe amplifying market volatility.
Speaker 1: Yeah, the flash crash worries those.
Speaker 2: Kinds of concerns, but the ability to train extensively in
Speaker 2: virtual environments first is a huge advantage for RL and finance.
Speaker 1: Just quickly, the key concepts in ROL you hear about
Speaker 1: are the agent that's the bot itself, the learner right,
Speaker 1: the action it takes buy, sell, hold, each step or
Speaker 1: update in the environments state, the state itself representing current
Speaker 1: market conditions, maybe price volume indicators, the reward it gets
Speaker 1: usually tied to financial returns profit or loss. And then
Speaker 1: algorithms like q learning, which is a popular method for
Speaker 1: the agent to figure out the optimal action to take
Speaker 1: in any given state to maximize future rewards.
Speaker 2: Okay, learning through rewards in the simulated world makes sense. Now,
Speaker 2: once you've trained these potentially complex AI strategies, how do
Speaker 2: you actually test them? How do you know if they'll work? Ah?
Speaker 1: Back testing crucial step. The source distinguishes between two main
Speaker 1: approaches here, vectorized back testing and event based back testing.
Speaker 2: Vectorized versus event based what's the difference? Vectorized back testing
Speaker 2: is usually faster. It processes all the historical data kind
Speaker 2: of at once, using efficient array operations. It's great for
Speaker 2: getting a quick high level overview of a strategy's overall
Speaker 2: performance like total return sharp a ratio, but it's generally
Speaker 2: less flexible for modeling more intricate realistic scenarios.
Speaker 1: Okay, fast, but maybe too simple sometimes could be event.
Speaker 2: Based back testing. On the other hand, simulate the market
Speaker 2: tick by tick or bar by bar. It processes events
Speaker 2: like a new price update or an order getting filled
Speaker 2: one by one sequentially.
Speaker 1: More like how trading actually happens exactly.
Speaker 2: This offers a much higher degree of flexibility. It allows
Speaker 2: you to model complex decision rules, incorporate sophisticated risk management logic,
Speaker 2: account for things like transaction costs and slippage more accurately.
Speaker 2: It really lets you zoom in on the details and
Speaker 2: understand how the bot behaves under specific market conditions. It's
Speaker 2: usually slower, but often gives a more realistic picture, which
Speaker 2: is vital before you risk real capital.
Speaker 1: Right. Realism matters. And speaking of risk management, how sophisticated
Speaker 1: can these AI powered trading bots get? Can they incorporate
Speaker 1: those crucial risk measures to protect against big losses? Oh?
Speaker 2: Absolutely, they can and arguably should utilize standard risk management
Speaker 2: tools just like human traders do, only perhaps more consistently
Speaker 2: and quickly, like stop losses, Yes, definitely, Stop loss orders
Speaker 2: SLS to automatically exit a position if the price moves
Speaker 2: against it by a certain amount, limiting the potential loss,
Speaker 2: and also trailing stop laws orders tsls.
Speaker 1: How do those work?
Speaker 2: A TSL automatically adjusts the stop level upwards as the
Speaker 2: price moves in your favor. So if you're long and
Speaker 2: the price goes up, the stop loss trails behind it,
Speaker 2: locking in some of the gains while still protecting against
Speaker 2: a reversal.
Speaker 1: Clever locks in profit, but keeps the up side open exactly.
Speaker 2: And of course they also use take profit orders tps
Speaker 2: to automatically exit a position in secure games once a
Speaker 2: pre defined target price is reached.
Speaker 1: So standard tools but may be applied more systematically by.
Speaker 2: The bot right and a common and quite smart practice
Speaker 2: mentioned for setting the levels for these stops and profit
Speaker 2: targets is to relate them somehow to the market's recent volatility,
Speaker 2: often using a measure like the average true range or
Speaker 2: ATR ATR. Why use that because it gives you a
Speaker 2: sense of the typical daily or intra day price movement
Speaker 2: the market noise. By setting your stop loss, say a
Speaker 2: multiple of the ATR away from your entry price, you
Speaker 2: try to avoid getting stopped out prematurely just because of
Speaker 2: normal random market fluctuations. You give the trade room to breathe,
Speaker 2: but still have.
Speaker 1: Protection ah avoiding the noise.
Speaker 2: That makes sense, it does, But it's also important to
Speaker 2: note something the source points out. While incorporating robust risk
Speaker 2: measures like stops is absolutely essential for survival and managing drawdowns,
Speaker 2: it doesn't always prove the strategy's net performance on its own.
Speaker 1: Really why not?
Speaker 2: Well, sometimes stops might cut winning trades short or lock
Speaker 2: in small losses. Frequently, there's often a trade off between
Speaker 2: risk reduction and potential return. As the saying goes, there's
Speaker 2: really no such thing as a free lunch. Even in
Speaker 2: risk management. You usually give up something to get that protection.
Speaker 1: Right, No free lunch, got it? And for actually doing
Speaker 1: this for the real world application? Are there platforms for this?
Speaker 2: Yes? The source mentions platforms like Awanda, which is a
Speaker 2: well known broker. They provide APIs that allow traders to
Speaker 2: access both historical data for back testing and training and
Speaker 2: real time data streams for deploying these trading bots live
Speaker 2: in the market. That allows for that crucial transition from
Speaker 2: simulation to actual market interaction.
Speaker 1: Okay, so the tools and platforms are there now. The
Speaker 1: financial market isn't just complex It's a really high space,
Speaker 1: extremely competitive environment, isn't it, which makes it seem like
Speaker 1: a natural battleground for these AI systems. It's a race
Speaker 1: for advantage.
Speaker 2: It absolutely is. You nailed it. Financial services companies are
Speaker 2: rapidly embracing AI, not just for trading but across the
Speaker 2: board to automate routine tasks, freeing up humans to analyze
Speaker 2: those colossal amounts of data at speeds and scales humans
Speaker 2: just can't match, to drastically improve customer service think chatbots
Speaker 2: and personalized advice, and even to ensure compliance with complex,
Speaker 2: ever evolving regulations.
Speaker 1: So it's not just about alpha about trading profits. It's
Speaker 1: about efficiency and compliance too, exactly.
Speaker 2: It's becoming fundamental to operations. But yes, the edge in
Speaker 2: trading is a huge driver. This isn't just about efficiency,
Speaker 2: It's really about gaining a definitive competitive edge in a
Speaker 2: zero sum or near zero sum game.
Speaker 1: Okay, if we connect this competition to the bigger picture,
Speaker 1: what does this whole AI revolution mean for the financial
Speaker 1: industry's most critical resources? Are we seeing new kinds of
Speaker 1: bottlenecks emerge because everyone's chasing the same AI dream.
Speaker 2: We are indeed seeing intense competition, a real race for
Speaker 2: probably three primary resources. Firstly, as you might guess, AI
Speaker 2: experts themselves, finding and retaining top talent and AI machine
Speaker 2: learning data science. It's a significant bottleneck. Financial firms are
Speaker 2: competing fiercely, not just with each other, but also with
Speaker 2: the big tech giants and nimble startups all wanting the
Speaker 2: same people. The talent war definitely. Secondly, there's the ongoing
Speaker 2: competition for specialized hardware. The demand for those powerful GPUs
Speaker 2: and TPUs we talked about is still incredibly high, and
Speaker 2: there's interest in newer, even more specialized chips like graphcoreps IPUs,
Speaker 2: which are designed specifically for AI. The source mentions major
Speaker 2: head funds like Citadel or even conducting their own cutting
Speaker 2: edge research into hardware optimization. That's how critical it is.
Speaker 1: They're researching chips now. Wow.
Speaker 2: Yeah. And Thirdly, there's that continuous aggressive search for novel
Speaker 2: and exclusive alternative data sources. Yeah, finding data that others
Speaker 2: don't have, data that offers unique proprietary insights. That's a
Speaker 2: constant battle. The value of standard data gets competed away quickly,
Speaker 2: so the hunt for unique out from unique data is relentless.
Speaker 1: Talent hardware and unique data, the new frontiers of competition.
Speaker 2: Absolutely, Yet despite all this intense activity and investment, the
Speaker 2: source makes a really interesting argument that AI in finance
Speaker 2: is still, in many ways in a nascent stage.
Speaker 1: Nascent really with all this going.
Speaker 2: On, relatively speaking, yes, it argues there's still a notable
Speaker 2: lack of standardization across the industry in terms of tools, techniques,
Speaker 2: best practices compared to maybe other fields where AI is
Speaker 2: more mature, and this lack of standardization paradoxically leaves the
Speaker 2: competitive landscape potentially wide open. It means there's still significant
Speaker 2: opportunity for nimble firms or firms with a breakthrough approach
Speaker 2: to gain truly significant, maybe even outsized advantages before things
Speaker 2: become more settled than standardized. The rules of the game
Speaker 2: are still being written in a sense.
Speaker 1: That's a fascinating point about the nascent stage. It makes
Speaker 1: me wonder about the ultimate consequence maybe the endgame for
Speaker 1: this AI race and finance. Could this eventually lead to
Speaker 1: something like a financial singularity where human intuition or traditional
Speaker 1: analysis is just completely overshadowed.
Speaker 2: It's a really compelling thought, isn't it. The source actually
Speaker 2: introduces a specific concept here an artificial financial intelligence or AFI.
Speaker 1: AFI okay distinct from AGI.
Speaker 2: Yes, very distinct. An AFI is defined as an AI
Speaker 2: that is consistently superior in this specific domain of trading
Speaker 2: and financial market analysis. Crucially, the argument is that an
Speaker 2: AFI does not necessarily require achieving human level general intelligence
Speaker 2: or human brain emulation or even physical embody mass.
Speaker 1: So it doesn't need to be like a person.
Speaker 2: No, it just needs to be better at finance. This
Speaker 2: makes it a much more specific and arguably a much
Speaker 2: more achievable goal in the nearer term than a full
Speaker 2: blown artificial general intelligence or superintelligence.
Speaker 1: This needs to be good at the finance game.
Speaker 2: Exactly, and the key takeaway here is profound well. Traditional
Speaker 2: econometric methods and even human traders today often struggle to
Speaker 2: find what the source calls microroscopic alpha, those tiny, fleeting
Speaker 2: statistical inefficiencies that might only yield a fraction of a
Speaker 2: percent gain on a single trade, the scrap's leftover sort of. Yeah, AI,
Speaker 2: with its ability to process vast data and complex patterns,
Speaker 2: offers a completely new, potentially much more powerful path for
Speaker 2: discovering that alpha, maybe even alpha that isn't so microscopic.
Speaker 2: It's like having a new kind of microscope or maybe
Speaker 2: even a completely new way of mining that lets you
Speaker 2: find valuable brains of gold where human intuition and older
Speaker 2: tools were only looking for obvious nuggets.
Speaker 1: A new paths to finding value that was hidden before.
Speaker 2: Wow.
Speaker 1: Okay, well you've just taken us on a real deep
Speaker 1: dive into AI and finance. We've seen how it's really
Speaker 1: not just another tool, but potentially a fundamental shift.
Speaker 2: It really feels that way.
Speaker 1: From redefining intelligence itself with things like ALFA zero, challenging
Speaker 1: those old elegant financial theories, to powering these incredibly sophisticated
Speaker 1: trading bods and completely reshaping competition in the industry, AI
Speaker 1: is clearly here to stay, and it feels like it's
Speaker 1: just getting started in finance.
Speaker 2: Absolutely, the potential impact is immense.
Speaker 1: So maybe a final thought for our listener, for you
Speaker 1: to maul over if these AI systems can eventually discover
Speaker 1: statistical inefficiencies that human design models and maybe even human
Speaker 1: intuition consistently miss, and if this artificial financial intelligence, this AFI,
Speaker 1: doesn't actually need to be embodied or think like a
Speaker 1: human or emulate a human brain to be superior, specifically
Speaker 1: at trading. What does that ultimately imply about the limits
Speaker 1: of our own human intuition when faced with truly data driven,
Speaker 1: powerful machine intelligence in the realm of finance, that
Speaker 2: Is the question, isn't it something to really think about?
