Duan Yongping revealed Micron Technology's options holdings: sold the Put and was allotted shares

Comparing news, Duan Yongping, a well-known investor, posted an article on Snowball with pictures disclosing his Micron Technology (MU) related positions. He said that people who buy short-term options are probably gambling; the seller is probably just an insurance company or a casino. The key is to rely on rules to control odds; selling Put relies on understanding the business (that is, probability or win).

He emphasized not to try to win every game, but don't touch anything you don't understand. The picture shows that its recent transaction records include: multiple Micron Put options due in August due to expiration; selling 100 $870 Call options due on August 26, for a transaction price of $37.55, receiving approximately $375,500 in royalties; and being placed to buy 10,000 shares of Micron shares due to the exercise of Put on August 10, at a cost of $870, for a total amount of $8.7 million.
