Backtest
The backtest results reveal that BK's earnings beats lead to strong positive returns and high win rates, reaching 7.56% return at 30 days with a perfect 100% win rate. Conversely, earnings misses show weak short-term performance but some recovery potential by 30 days. Industry-wide, earnings beats and misses in the Capital Markets sector have negligible impact on stock prices. This suggests that BK's earnings surprises are significant for its stock performance, while industry reactions remain muted. Investors may benefit from holding BK shares after earnings beats and adopting a cautious, medium-term approach after misses.
