Risk management through stop loss strategies

Stop Loss Overview
A stop-loss order is an instruction placed with a broker to sell (or buy) if a security reaches a predetermined price, designed to limit losses. In the trading world, stops are viewed as essential risk control and money management tools.
However, the reality of stop-loss implementation is more complex than commonly understood. While stops provide protection against large losses, they also fundamentally alter the return distribution and can reduce expected returns.
Understanding the hidden costs and mathematical implications of stop-loss orders is crucial for developing effective trading strategies that balance risk management with profit potential.

Trade-off: exchange expected returns for reduced tail risk and predictable loss distributions✓
Stop placement methods: fixed percentage, volatility-based, ATR, support/resistance levels✓
