The asymmetry of losses, the recovery math, and the real reason to protect capital
Published by The Retail Trader · AUG 09, 2026 · Features
This is perhaps the most important math in trading, and it is school-level math. Even so, the cost of not knowing it runs into lakhs.
If ₹100 falls 50%, ₹50 is left. Now to get back from ₹50 to ₹100 you need not 50% but 100%. Loss and recovery are not equal, and the gap keeps widening as the loss gets bigger.
The whole picture:
• After -10% — about +11% is needed. Easy.
• After -20% — +25%.
• After -33% — +50%.
• After -50% — +100%. You have to double your money just to get back to where you were.
• After -75% — +300%. That is almost a new life.
Avoiding big losses is more valuable than making big wins. A trader who never falls more than 20% overtakes one who doubles in two years and halves in the third.
That is why the whole point of risk management is not 'earning less'. The point is to keep losses from entering the zone where the math itself turns against you.
Besides depth, there is another measure: how many days the account has gone without making a new high. This is the part that breaks people.
A 15% drawdown that drags on for two years is far heavier than a 30% drawdown that fills in three months. In the first, people abandon the system — often just when it was about to start working again.
A common framework:
• Per trade — a small fixed percentage of capital.
• Per day — once you lose this much in a day, the screen goes off. This stops revenge trading.
• Per week or month — if you fall more than this, cut size in half, or stop trading and review.
• Total — a level at which you halt the whole system and rethink, rather than trying to 'win it back'.
Increasing size during a drawdown is the most natural and the most deadly reaction. The math runs the other way: taking bigger size in a falling account means you now have fewer chances to be right. The right answer is always the opposite — make it smaller, go slower, and find the cause first.
