#Risk Management#Position Sizing#Drawdown#Kelly Criterion

Executive Brief

Key Takeaways

01.Risk management must be integrated directly into position sizing algorithms.
02.The Kelly Criterion offers theoretical optimal growth but requires fractional sizing (Half Kelly) in practice.
03.Stop-losses, drawdown caps, and factor correlation limits protect against fat-tail events.

Core Quant Risk Principles

Quantitative risk management uses statistical measures (VaR, Expected Shortfall, volatility limits, factor exposures) to limit potential losses, control leverage, and prevent ruin.

Even a strategy with a high Sharpe ratio can suffer catastrophic loss without proper position sizing and stop-loss rules.

Frequently Asked Questions

What is fractional Kelly sizing?

Fractional Kelly (e.g., 25% to 50% of the Kelly formula target) reduces portfolio variance and protects against parameter estimation errors.
