At noon, I went out to eat with a friend who plays Big A. He complained to me, saying that the money he earned over a year was wiped out in July. I checked his account—just in July, he suffered 4 daily-limit down moves, and they were all heavy positions. His floating loss was more than 170 million. I asked him why he didn’t cut his losses in time. He said he wanted to cut losses too; but his large positions couldn’t be closed out in time. When the smaller positions finally came out, he wanted to pick up the bottom to lose less. In the end, he bought at the halfway point up the mountainside. Now he still doesn’t know what to do, and he asked me for my opinion. I told him I don’t know either.
