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 | -47.7% | -23.5% | 19.5% |
| 3Y History | -76.5% | -28.4% | 50.0% |
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 Palo Alto Networks stock compared with the stock performance of peers that reported earnings just before Palo Alto Networks. For fair comparison, peer stock returns also represent post-earnings one-day (1D) returns.
