Backtest
The backtest results indicate that JPMorgan Chase's earnings beats lead to strong medium-term gains with a 90% win rate and 4.5% average return over 30 days, while earnings misses surprisingly also yield positive returns, peaking at 10.7% over 30 days. Industry reactions vary, with Construction and Engineering benefiting from both beats and misses, whereas Food Products and Professional Services show negative impacts. This suggests that investors can capitalize on JPM earnings events by focusing on sector rotation strategies, overweighting economically sensitive industries after beats and misses, and considering JPM's resilience even after earnings disappointments.
