This is how it feels to me: once the amount of capital reaches a certain level, it’s actually correct no matter what you buy.

According to reports, because Duan Yongping isn’t familiar with the rules for Hong Kong stock index options, when he sold Bubble Mart put options (puts), he made a “blunder.” He had planned to sell a position of 3.4 billion HKD, but by mistakenly treating each Hong Kong option contract as covering 200 shares instead of 100 shares like in US stocks, the actual sold size doubled to 6.7 billion HKD.
The option strike price is 150 HKD, it expires on April 29, and the 14-day premium yield is 2.18%, with an annualized return as high as 57%. This move is effectively like committing to take the stock if the price falls below 150 HKD, creating a strong “price support,” putting the bears in a bind: either shorting is met with resistance, or if they don’t short they still have to pay interest—so much so that some bears even filed a complaint with the Hong Kong Securities and Futures Commission.
1. I’m just an amateur. I didn’t know one deal is 200 shares; I accidentally bought too much by a factor of two—one slip and I’m talking about 6 billion.
2. The reason for selling puts is that you have to think about what stock to use to make the exchange.
I understand—last week I slipped up when ordering takeout and clicked for two orders by mistake, and I didn’t request a refund either. After all, it was only about 50 dollars. $ETH
