Punchline: the return-to-trough ratio (“RtT”) attempts to measure return generated relative to maximum pain incurred. Computationally, RtT = return, divided by, worst drawdown. The following table computes the RtT for hedge fund strategies.
The trailing 7-year (Jan 2010 – Dec 2016; post GFC drawdown and aftermath) return-to-trough ratio (“RtT”) for Hedge Fund Research’s monthly HFRI hedge fund strategy indices, ranked by annualized RtT, are shown below:
Computationally, RtT = return, divided by, worst drawdown. In its raw form it uses cumulative returns and worst drawdown over the horizon detailed. However, the raw cumulative RtT can be somewhat amplified as horizon length increases as returns cumulate with time while volatility, which begets drawdown, tends to expand with the square root of time. Hence, annual-equivalent RtT, my preferred poison, uses annualized returns in the numerator and worst drawdown, deflated by the square root of the investment horizon, in the denominator. By creating a level-time playing field annual-equivalent RtT can help facilitate comparison; both cross sectional between assets as well inter temporal for the same asset.
