Drawdown recovery

Shows the gain needed to climb back to even after a drawdown, always more than the fall. Use it when setting a maximum drawdown limit.

The asymmetry between losses and gains is the most important arithmetic in risk management, and it catches almost everyone the first time. If you lose twenty percent, you are not twenty percent away from where you started. You are on a smaller base, so the gain has to be measured against that smaller base, and it takes twenty five percent to get back. The deeper the hole, the worse the ratio gets, and it gets worse quickly.

The recovery multiple row makes the pattern visible. At small drawdowns it sits just above one, meaning the gain needed is barely more than the loss taken. By thirty percent it is about 1.4. By fifty percent it is two, and by eighty percent it is five. That curve is why professional risk limits tend to sit at levels that look conservative from the outside. They are not pessimism, they are an acknowledgement that recovery gets disproportionately harder the further you fall.

This is also the argument for cutting size during a drawdown rather than increasing it. The instinct after losses is to trade bigger to win it back faster, which is exactly the move the arithmetic punishes. Trading smaller while down means the recovery is slower in percentage terms but the floor is much further away, and staying in the game is the precondition for any recovery at all.

Use the card in advance rather than in the middle of a bad run. Pick the drawdown at which you would stop trading and rebuild the plan, look at the gain it would demand, and ask honestly whether you believe your edge can deliver it in a reasonable time. If the answer is no, the limit is too deep and belongs somewhere shallower.
