Duan Yongping disclosed Micron Technology's options position and received shares after selling puts

Famous investor Duan Yongping posted on Xueqiu with images revealing his holdings related to Micron Technology (MU). He stated that those buying short-term options are likely gambling, while those selling are probably just insurance companies or have opened a casino, with the key being to control the odds through rules; selling puts relies on understanding the business (i.e., probability or winning edge). He emphasized not to expect to win every time, but definitely avoid things you don't understand.

The images show his recent trading records, including: multiple holdings of Micron's $870 put options expiring in August that expired worthless; on August 11, he sold 100 contracts of the $870 call options expiring on August 26 at a transaction price of $37.55, earning approximately $375,500 in premiums; on August 10, due to being exercised on the put, he was allocated to buy 10,000 shares of Micron stock at a cost price of $870, totaling $8.7 million.
