Abstract: Hang Seng Indexes announced the May review results after market close, and three ADD-NEW names enter implementation. Chalco and BeOne reversed their announcement-day gains through the bridge; J&T Express kept a positive bridge return. Historical ADDs with negative bridge returns had weaker first-week outcomes, while positive-bridge ADDs had mixed first-week outcomes.
