Hit Ratio is the percentage of individual stock picks (or active decisions) that outperformed the benchmark or made a positive contribution — a measure of a fund manager's decision-making accuracy.
Hit Ratio = Number of winning bets ÷ Total bets × 100. For a mutual fund manager, a 'bet' is any position that differs from the benchmark — overweights, underweights, and exclusions. A Hit Ratio of 60% means 6 out of every 10 active positions contributed positively to alpha. Hit Ratio alone is insufficient — a manager can have a 40% Hit Ratio but still deliver strong alpha if their winners are much larger than their losers (high Win/Loss ratio). Both metrics together define manager quality.
Hit Ratio is the fund manager's 'batting average' — what percentage of their investment calls were right. A fund manager with a 65% Hit Ratio makes the right call on 65 out of 100 positions. This is actually quite high — even legendary investors like Warren Buffett have hit ratios in this range. The key is that winners should be meaningfully larger than losers. A manager with 50% Hit Ratio but 3x win/loss can still deliver great returns.
Identify all active positions (overweight and underweight vs benchmark).
Count positions that contributed positively to alpha (winners).
Hit Ratio = Winners ÷ Total positions × 100.
Strong performance = Hit Ratio 55–65% AND wins being larger than losses.
