Abstract: CSI announced four ADDs and four DELETEs for STAR50, effective 15 Jun 2026. Bridge-window data is complete through 12 Jun 2026. Yuanjie Semi led the ADD bridge gains, while Hua Hong Semiconductor reversed its pre-announcement gains. SICC had the weakest bridge performance among the DELETEs. Historically, positive-bridge ADDs averaged weaker first-week returns. Negative-bridge DELETEs showed the most consistent first-week losses.
