High-Water Marks and Fee Drag

Many hedge funds charge a performance fee — commonly around 20% of profits — on top of a management fee. Without a safeguard, a fund that loses 20% one year and then gains 20% the next would be back to breakeven for the investor, yet the manager could still collect a performance fee on that second year's "gain" even though the investor has made no actual money overall. A high-water mark prevents this: the manager only earns a performance fee on gains that push the fund's value above its previous peak, so after a loss the fund must first recover fully back to its old high before any new performance fee is charged again.

"Fee drag" describes the broader cost this fee structure imposes over time: even a fund that performs well can see a meaningful chunk of its raw returns eaten by combined management and performance fees, especially when both fees compound over many years. For example, a fund that peaks at $120 per share, drops to $100, and later climbs back to $130 only owes a performance fee on the $10 above the old $120 peak, not on the full $30 recovery from the $100 low — the investor isn't charged twice for the same ground already covered before the loss.
