Foolish take
Yiheng invests in a variety of industries, which means the Planet Fitness holding was probably not unusual. It also commonly holds stock options along with stocks, with four of its 27 holdings consisting of options in the third quarter of 2025.
By holding put options in Planet Fitness, Yiheng Capital had bet the price of the stock would go down. During the third quarter, Planet Fitness’s stock price had fallen modestly.
Put options give an investor the right to sell a stock at a fixed price until the option’s expiration date. However, such instruments can fall in value if the stock trades in a range or does not move significantly.
This appears to have happened with the Planet Fitness options. While the stock price fell during the third quarter, the change in price was modest, indicating it may not have fallen far enough for the put options to become profitable.
