A small number of people have already tried to short Yitai, hoping that it will not pass or that after passing, the good news will fall like the big cake for a few days. I can only say that there is no need to take this risk, just keep your contract short. The big cake ETF has experienced ups and downs. In the end, when the big cake passed, it also rose sharply and then fell. I remember clearly that the big cake passed and then fell back. Yitai pulled up ten points on that day and broke through the 2000+ range. At that time, it was believed that the big cake ETF passed, and Yitai would hype the ETF expectations and pull the market. At that time, there was a differentiation, and the contract was in a mess and couldn't cope with it.
