When the market is bad and the risk is too high, the position will definitely be greatly reduced. Or the banker intends to withdraw funds after doing a wave, which will also greatly reduce the position. A substantial lightening is not necessarily a collective lightening, because the banker has a large share of funds. As you said, the collective substantial reduction of positions should refer to the collective substantial reduction of positions in related industrial chains or related varieties in multiple industrial chains. This is the problem that the market is hard to escape. Just like a few days ago, the stock market was not good, causing panic and reducing stocks.
