Correlation Between 1D, 5D and 21D Historical Returns
A relatively less risky strategy (though not useful if the correlation is low) is to understand the correlation between short-term and medium-term returns post earnings, find a pair that has the highest correlation, and execute the appropriate trade. For example, if 1D and 5D show the highest correlation, a trader can position themselves “long” for the next 5 days if the 1D post-earnings return is positive. Here is some correlation data based on a 5-year and a 3-year (more recent) history. Note that the correlation 1D_5D refers to the correlation between 1D post-earnings returns and subsequent 5D returns.
| History | 1D_5D Returns | 1D_21D Returns | 5D_21D Returns |
|---|---|---|---|
| 5Y History | -14.7% | -3.1% | 25.0% |
| 3Y History | -49.7% | 23.6% | 60.9% |
Is There Any Correlation With Peer Earnings?
Sometimes, peer performance can have an influence on post-earnings stock reaction. In fact, the pricing-in might begin before the earnings are announced. Here is some historical data on the past post-earnings performance of Occidental Petroleum stock compared with the stock performance of peers that reported earnings just before Occidental Petroleum. For fair comparison, peer stock returns also represent post-earnings one-day (1D) returns.
