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. The strongest relationship over five years is between the 1D and the following 21 days, at 0.45 across 19 releases: the early move has tended to continue in the same direction. That is a tendency, not a rule, and it can break on any given report.
| History | 1D vs next 5D | 1D vs next 21D | 5D vs next 21D |
|---|---|---|---|
| 5 Years | 0.14 | 0.45 | 0.31 |
| 3 Years | 0.19 | 0.44 | 0.25 |
Do Peers That Report First Offer A Clue?
Merck (MRK), IDEXX Laboratories (IDXX) and Neogen (NEOG) usually report about 6 to 27 days before Elanco Animal Health, and have already reported this season. This time Merck rose 3.8% on its October 29 report, IDEXX jumped 22% on its November 2 report, and Neogen fell 2.3% after its October 6 report. The table compares each peer’s one-day reaction to its own earnings with Elanco Animal Health’s one-day reaction to the report that followed. The correlations are MRK (0.17), IDXX (0.12), NEOG (-0.84); the closer to 1, the more the peer’s reaction has foreshadowed Elanco Animal Health’s, and a clearly negative value means it has tended to point the other way.
