A U.S. ban on new Chinese data center equipment imports could raise costs for U.S. cloud computing firms including Amazon Web Services (AWS, AMZN.O), forcing them to switch to alternative suppliers such as U.S.-based Coherent (COHR.N) and Lumentum (LITE.O).

Duan Yongping once again responded on Xueqiu to his recent reduction in Pop Mart positions, elaborating on his long-term holding strategy: "It’s mainly because the put options I sold expired, which significantly impacted my shareholding ratio. Additionally, for some of the stocks I purchased, I simultaneously sold call options at the time of buying, and the counterparty ended up exercising the right to 'call away' those shares. Going forward, as long as the stock price stays within a certain range, I may continue this approach. From the start, I said 'Pop Mart Insurance Company has opened', but many people didn’t actually grasp what that meant." The Hong Kong Stock Exchange disclosed today that H&H International Investment, managed by Duan Yongping, cut its long position in Pop Mart International Group Limited from 7.65% to 5.55% on July 30, 2026. Following the expiration and exercise of some call options on July 30, Duan was obligated to deliver shares at the agreed price, leading to a reduction in his physical shareholding. The exercise involved delivering a portion of the shares at a combined settlement price of approximately HKD 162.50, resulting in a net decrease of around 8.9328 million physical shares. BlockBeats Note: Duan Yongping stated in April this year that "Pop Mart Insurance Company has opened", referring to his official initiation of selling put options on Pop Mart. He positions himself as an insurance company that collects "premiums" (option premiums) from other traders upfront: if the stock price falls, he buys shares at a lower price; if not, he earns the option premiums.
