Do Early Post-Earnings Moves Continue?
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, all of these correlations are below 0.40 in absolute terms, so the early post-earnings move has not reliably predicted what followed. Over the last three years the link is stronger, at 0.44 and 0.59, but that rests on only 11 releases.
| History | 1D vs next 5D | 1D vs next 21D | 5D vs next 21D |
|---|---|---|---|
| 5 Years | -0.01 | 0.14 | 0.32 |
| 3 Years | 0.00 | 0.44 | 0.59 |
