The Markets will Never Be the Same - AI Takeover

AI's Impact on Investing and Trading
📌 The fear of AI destroying industries is evident, with IBM's stock falling 12% due to AI capability claims regarding legacy code like Cobalt.
🤖 A Harvard study found that AI can predict 71% of trades occurring in actively managed portfolios, suggesting significant disruption in financial advice.
📉 The potential for an army of smarter AI bots absorbing all profit opportunities by achieving perfect market efficiency is discussed but ultimately dismissed as impossible.

Democratization and Access via AI
🌐 Technology, particularly driven by AI, will accelerate the global access to investing in public markets, benefiting the 8 billion people currently without access.
📈 Stock market participation in the US is about 62%, significantly higher than Australia (37%) or Sweden (22%), largely due to accessible technology like free apps.
💡 Tools and planning historically reserved for high-net-worth individuals, such as tax loss harvesting, will become virtually free and accessible to everyone through AI-enhanced platforms like robo-advisors.

Market Dynamics and Alpha Disappearance
💸 Easy alpha (positive ROI) will largely disappear as AI bots replicate the best trading skills, similar to how historical edges, like stocks trading below book value per Benjamin Graham, were eventually arbitraged away.
🎢 Expect larger episodes of extreme volatility, including flash crashes, due to phenomena like overfitting (finding patterns in random market noise) and the adoption of spurious correlations by AI agents using vast, diverse datasets.
🛑 Similarities in AI decision-making regarding risk parameters or margin limits will amplify forced liquidations, similar to what causes current flash crashes.

Human Control and Market Inefficiency
⚙️ Humans will remain in control because investment goals are diverse (e.g., risk mitigation, income generation, immediate cash withdrawal for a house down payment), preventing perfect market alignment.
Paradoxically, perfect market efficiency is impossible due to the Grossman-Stiglitz paradox: if a market were perfectly efficient (price equals true value), there would be no profit (alpha) in making it efficient, leading participants to leave, thus reintroducing inefficiency.
💰 AI will lead to a larger distribution between average and extraordinary returns; achieving average market returns will become easier, while beating the market will be much harder.
👑 Highly successful investors with massive capital (e.g., Berkshire Hathaway with $$344$ billion in cash) price themselves out of smaller, high-ROI opportunities, leaving those opportunities available for smaller retail investors who cannot move the market price with their trade size.

Key Points & Insights
➡️ AI will increase global access to public market investing, helping more people escape poverty through technology democratization.
➡️ Prepare for increased market volatility caused by shared AI strategies reacting simultaneously to similar data inputs or constraints.
➡️ Average returns will be easier to achieve, but extraordinary returns will require greater difficulty, though large pools of capital inadvertently create opportunities for smaller investors.
➡️ The Grossman-Stiglitz paradox ensures markets can never reach perfect efficiency because the profit motive for achieving efficiency would disappear if efficiency were reached.
