Prueba retrospectiva
The backtest results show that AXP exhibits a strong positive performance after earnings beats, with an 81.82% win rate and a 4.71% average return over 30 days. Short-term gains are also positive but more modest, indicating steady appreciation post-earnings surprise.
This suggests that AXP's stock benefits significantly from earnings beats, unlike the broader Consumer Finance industry, which shows no meaningful price reaction. Holding AXP shares for up to 30 days post-earnings beat appears advantageous.
Investors might consider leveraging AXP earnings beats as a reliable signal for medium-term gains, while being cautious about generalizing this to the entire industry.
