Brokerage firms became the main target of short selling today, with a drop of -3.65%. The reason is very simple. There are too many retail investors and they cannot be pulled up. They must be washed out. As the saying goes, no matter how they are washed, I will not get off the bus. Brokerage firms may be late in the bull market, but they will not be absent. Hold on patiently. Secondly, the more bullish the market is, the more risk you can resist by buying brokerage firms.
