Correlation Between 1D, 5D And 21D Post-Earnings Returns
Another approach is to wait for the initial reaction and ask whether it tends to continue. The table below shows the correlation between the 1D return and the return over the following 5 and 21 trading days, and between the 5D return and the following 21 trading days. A value near 1 means the first move has tended to continue; near -1, to reverse; near 0, no consistent pattern. Over five years, none of these correlations is strong enough to trade on: all are below 0.40 in absolute terms. Over the last three years, the correlation between the 5D return and the following 21 days reached 0.48, though this rests on a small sample of just 12 releases and remains statistically weak.
| History | 1D vs next 5D | 1D vs next 21D | 5D vs next 21D |
|---|---|---|---|
| 5 Years | 0.09 | -0.03 | -0.01 |
| 3 Years | 0.02 | 0.17 | 0.48 |
An earnings release can move one stock sharply in either direction. A diversified portfolio spreads that risk.
