Backtest
The backtest results show that AXP achieves a 75% win rate and a 3.89% average return over 30 days following an earnings beat, indicating a positive market reaction. However, the Consumer Finance industry overall shows no significant price movement after earnings beats, suggesting limited sector-wide impact. Additionally, AXP's earnings beat benefits the Transportation Infrastructure industry but negatively affects Leisure Products, highlighting varied sector responses. Investors may consider holding AXP shares for up to a month post-earnings beat and adjusting sector exposure accordingly to capitalize on these differentiated effects.
