Prueba retrospectiva
The backtest results indicate that AXP shows a strong positive price reaction following earnings beats, with a 70% win rate over 3 days and returns peaking at 3.23% over 30 days. In contrast, the Consumer Finance industry overall exhibits minimal impact from earnings beats or misses, with returns under 3.3% and no significant price movements. This suggests that AXP's earnings beats are a more reliable indicator of stock performance than industry-wide earnings events. Investors may benefit from focusing on AXP's earnings beats for medium-term gains rather than relying on broader industry trends.
