The backtest results show that COST consistently recovers from ex-dividend price drops with an average recovery duration of 1.33 days and a 100% recovery probability within 15 days over 12 dividend events. This indicates a strong and reliable price rebound pattern following dividend payouts. The analysis suggests that investors can expect a swift price normalization after the ex-dividend date, minimizing downside risk. Consequently, this pattern offers an opportunity for dividend-focused investors to confidently hold COST through ex-dividend periods, anticipating rapid recovery and stable returns.
