Backtest
The backtest results indicate that AXP shows a strong positive price reaction after earnings beats, with a 70% win rate within 3 days and an 80% win rate within 30 days, yielding a 3.23% average return over 30 days. In contrast, the Consumer Finance Industry overall does not exhibit significant price movements following earnings beats, with only modest returns observed. This suggests that AXP's earnings beats are a more reliable indicator of positive stock performance than the broader industry trend. Investors may benefit from holding AXP shares for up to a month post-earnings beat to capture gains.
