What this game teaches
Losses and gains are not symmetrical. If a portfolio falls 50%, a 50% gain does not restore it: it needs to double. The reason is that the recovery starts from a smaller base.
Example: a 40% loss needs 0.40 ÷ 0.60 = 66.7%
Up to about 20%, the gain needed is only a little larger than the loss. Beyond that it grows quickly: 75% needs 300%, and 90% needs 900%. That is why avoiding large losses matters more than catching large gains, and why the first rule of trading is to survive.
Real drawdowns in the NIFTY 50, 2019 to 2026
Every fall of 10% or more in the NIFTY 50 price index in our data set, with the time it took to regain the previous peak:
| Peak | Trough | Fall | Rise needed | Back at the peak | Months from trough |
|---|---|---|---|---|---|
| 14 Jan 2020 | 23 Mar 2020 | −38.4% | +62.4% | 9 Nov 2020 | 8 |
| 18 Oct 2021 | 17 Jun 2022 | −17.2% | +20.8% | 24 Nov 2022 | 5 |
| 26 Sep 2024 | 4 Mar 2025 | −15.8% | +18.7% | 2 Jan 2026 | 10 |
| 2 Jan 2026 | 30 Mar 2026 | −15.2% | +17.9% | Not yet recovered | – |
| 3 Jun 2019 | 19 Sep 2019 | −11.4% | +12.9% | 27 Nov 2019 | 2 |
The deepest fall in this period was 38.4%, from 14 Jan 2020 to 23 Mar 2020. An index investor who stayed invested needed a rise of 62.4% to get back. The most recent fall, from 2 Jan 2026, had not been fully recovered by the end of our data. Broad indices have so far recovered from every major fall, though sometimes slowly; individual stocks often never do. A trader using leverage at the bottom of such a fall may not survive to see the recovery.
Using this in practice
- For investors: decide your equity allocation by the fall you can live through without selling. If a 40% fall would make you sell, hold less equity. See the asset allocation guide.
- For traders: set a maximum drawdown (for example 15% to 20%) at which you stop and review, and size trades so that an ordinary losing streak cannot get near it. Try the blown-account challenge.
Frequently asked questions
What is a drawdown?
The fall in the value of a portfolio or index from its highest point to a later low, usually expressed as a percentage. The maximum drawdown is the largest such fall over a period.
How long do stock market recoveries take?
It varies widely. The NIFTY 50 table above shows recent examples. Some falls recovered within months; historically, some major indices have taken many years after big bubbles burst.
Does averaging down help recovery?
For a diversified index fund it can, because the index is likely to recover. For individual stocks it depends on whether the business is sound; averaging into a failing business increases the loss. Try the falling knife game.
