COSCO SHIP ENGY's stock plummeted 5.06% during intraday trading, reflecting heightened selling pressure in the market.

The sharp decline coincides with a major lock-up share release event, where approximately 347 million A-shares became eligible for trading, representing roughly 6.35% of the company's total share capital. This concentrated release of previously restricted shares has significantly increased supply in the market, intensifying short-term selling pressure.

Additionally, Executive Director and General Manager Zhu Maijin and Board Secretary Ni Yidan had previously disclosed plans to reduce their holdings, with their selling timing overlapping with the lock-up expiry, further weighing on investor sentiment. The company's scheduled review of Q1 results adds another layer of near-term uncertainty, while a planned substantial investment in two Panamax crude oil tankers raises capital expenditure concerns among investors.
