Drawdown
Drawdown is a measure of the decline in an investment or trading account from its historical peak to its lowest point before a new peak is achieved. It represents the potential risk and the emotional toll of a trading strategy, highlighting the worst-case performance an investor might have experienced.
In derivatives trading, managing drawdown is essential for maintaining capital and preventing margin calls. A strategy with high volatility and large drawdowns requires significant risk capital to survive periods of underperformance.
Analysts use metrics like the Calmar ratio to evaluate whether the returns generated by a strategy justify the drawdown experienced. Understanding the depth and duration of drawdowns is vital for effective risk management and portfolio construction.
