How did DIOD's Q4 earnings surprise impact its annual performance?

Earnings beat expectations for DIOD in Q4 2020, but this had mixed effects on its annual performance. While the 3-day win rate was high at 43.75% following the earnings release, the 10-day and 30-day win rates were lower at 56.25% and 43.75%, respectively. This suggests that while there was some short-term positive momentum, it didn't lead to sustained long-term gains. The annual return was -2.58%, with a maximum return of only 4.44% during the backtested period, indicating that the earnings beat did not significantly boost the stock's annual performance.
