• "I have a good feeling about this trade"
• Limited data considered
• Confidence from expertise

Post-AI Mindset:

• Decisions supported by data analysis

• "The data suggests this trade has edge"

• Comprehensive data synthesis

• Confidence from analysis

• Impact: More systematic decision-making, but potential over-reliance on data that AI might misinterpret.

Changed Risk Perception

Pre-AI Risk View:

• Risk assessed subjectively
• Based on personal experience
• Often underestimated or overestimated
• Fear and greed driven

Post-AI Risk View:

• Risk quantified by AI

• Based on comprehensive data

• More accurate (but not perfect)

• Data-rationalized but still emotional

• Impact: Better risk awareness, but potential false confidence in AI risk assessments.

Information Processing Shifts

Pre-AI Information:

• Limited sources processed
• Significant information asymmetry
• Time lag in information incorporation
• Expertise required for analysis

Post-AI Information:

• Vast sources processed instantly

• Reduced information asymmetry

• Technical patterns identified and traded instantly
• Fewer "easy" opportunities

Evidence:

• Reduced bid-ask spreads

• Faster price discovery

• Lower short-term volatility (usually)

• Harder to outperform benchmarks

• Implication: Simple strategies that worked before no longer work. Edge requires sophistication.

Liquidity Changes

Positive Effects:

• AI market makers provide tighter spreads
• More continuous liquidity
• Deeper markets in normal conditions

Negative Effects:

• Liquidity can vanish in stress (AI withdraws)

• Flash crashes more possible

• Correlated AI behavior creates gaps

• Net Effect: Better normal conditions, worse tail events.

New Volatility Patterns

Observations:

• Lower intraday volatility (AI smoothing)

• Higher event volatility (AI reacts simultaneously)

• New correlation patterns (AI creates linkages)

• Faster regime changes

• Trading Implication: Traditional volatility models may be less accurate as AI changes volatility dynamics.

Information Decay Acceleration

Pre-AI: Information edge could persist for days or weeks.

Post-AI: Information edge decays in minutes to hours.

• Implication: Speed matters more, or you need information AI can't access.

---

The Democratization Effect

AI is changing who can participate successfully in markets.

Access Revolution

Previously Required:

• Net Effect: Individual traders can now access capabilities previously reserved for institutions.

Skill Shift

Old Skill Premium:

• Data collection

New Behavioral Patterns Emerging

AI is creating new patterns in investor behavior.

Herding Amplification

What's Happening: When many traders use similar AI models:

• Signals converge
• Trades cluster
• Momentum amplifies
• Reversals become violent

Example: AI detects same pattern → all AI systems signal buy → crowded entry → vulnerable to reversal

• Trading Implication: Contrarian strategies may become more valuable as AI creates crowded consensus.

Reduced Heterogeneity

Pre-AI: Diverse approaches, beliefs, and timeframes provided market balance.

Post-AI: AI convergence toward optimal strategies reduces diversity.

• Risk: Markets need disagreement to function. Too much AI agreement could create instability.

Adaptation Acceleration

Pre-AI: Strategies persisted for years.

Post-AI: AI identifies and arbitrages edges faster.

• Implication: Strategy development must be continuous, not occasional.

New Alpha Sources

Declining Alpha:

• Technical pattern recognition
• Simple statistical arbitrage
• Information speed advantages

Growing Alpha:

• AI oversight (when to override)

• Novel information sources

• Narrative and context understanding

• AI-inefficient market segments

• Pattern: Alpha shifts from what AI does well to what AI does poorly.
