Backtest
The backtest results reveal that JPM shows strong positive returns following earnings beats, with an 88.89% win rate and a 4.64% average return over 30 days, while earnings misses surprisingly also yield consistent gains up to 10.70% at 30 days. The Banks Industry benefits moderately from earnings beats but shows little reaction to misses. This suggests JPM's stock is resilient and tends to appreciate regardless of earnings surprises, unlike the broader industry. Investors might consider buying JPM shares on earnings events and holding long term to maximize returns, while industry-wide moves are more subdued.
