Drawdown

Peak-to-trough decline of an investment's value during a specific period.

A drawdown measures the peak-to-trough decline in the value of an investment portfolio, fund, or individual asset over a specific time frame. It is typically expressed as a percentage from the highest historical valuation (the peak) to the lowest subsequent valuation (the trough) before a new peak is achieved. This metric helps investors understand the historical downside risk and volatility of an investment strategy. To calculate a drawdown, you identify the highest valuation point of an asset during a given period and track how far it falls before recovering to or exceeding that previous peak. A drawdown is only considered complete once the asset's price climbs back above the initial peak. Investors pay close attention to both the depth of the drawdown (how much value was lost) and the duration of the drawdown (how long it took to recover). For retail investors, analyzing historical drawdowns is crucial for assessing risk tolerance. While two funds might have the same average annual return, one might have achieved it with a maximum drawdown of 10%, while the other experienced a painful 40% drop. A deep drawdown can trigger panic selling, causing investors to lock in losses. It is also a critical input for calculating risk-adjusted performance metrics like the Sharpe ratio.

An investor buys a mutual fund that reaches a peak value of $10,000. Due to a market downturn, the fund's value declines to a low point of $7,500 before starting to recover. The drawdown is calculated as ($7,500 - $10,000) / $10,000 = -0.25, which represents a 25% drawdown.
