3 · Question of the week
Does a big buy after a big drop do better than either alone?
Not really. 45% vs 46%: less than 2 points apart.
| Beat the S&P 500 over 90 days | $1M+ after a 20%+ drop | every other buy |
|---|---|---|
| All years since 2020 | 45% (406 of 902) | 46% (7,330 of 15,997) |
| 2020 to March 2023 | 47% (243 of 522) | 47% (3,619 of 7,662) |
| April 2023 to now | 43% (163 of 380) | 45% (3,711 of 8,335) |
A pattern only counts here if it points the same way in both halves of the data. Median result and every case are in the Backtester. Survivorship caveat: delisted stocks often lack prices, which flatters these numbers a little.
