20. Maximizing Sharpe Ratio via AI Enhancements

Introduction
Sharpe ratio measures risk-adjusted return. AI offers multiple levers to boost this metric—ensemble models, volatility scaling, and hedging overlays.

Enhancement Techniques

1. Model Ensembles: Combine diverse algorithmic signals to smooth equity curves.

2. Volatility Scaling: Increase position size in low-volatility regimes and decrease in high-volatility regimes.

3. Tail-Risk Hedges: Add protective put options when drawdowns exceed a threshold (e.g., 5%).

4. Bayesian Optimization: Tune hyperparameters (e.g., lookback windows, stop levels) with Sharpe as the optimization objective.

Implementation Steps

• Build three distinct models (momentum, mean-reversion, fundamental).

• Use a meta-learner to allocate capital among them based on recent performance and regime detection.

• Integrate a volatility forecasting model to adjust overall leverage daily.

• Backtest with transaction costs and portfolio‐level P&L aggregation for Sharpe calculation.

Illustration
A single‐model momentum strategy had Sharpe 1.2; after ensembling, volatility scaling, and hedging, its Sharpe rose to 1.8 over a 7-year backtest.

Conclusion
By layering AI-driven enhancements—ensembles, risk scaling, and hedges—you can materially improve your strategy’s risk-adjusted returns and build more resilient portfolios.
