1. From the perspective of short-selling power, the shape of the stock index has been destroyed to a certain extent after heavy volume adjustment, and the chips of individual stocks have begun to loosen, and a considerable amount of funds are already in a quilt state. These quilt cover funds will become the resistance of the next round of market strength. Digest this part of the capital chips, or adjust the stock index sideways for a period of time, so that unstable investors can gradually leave the market and complete the cleanup of floating chips. Either greatly enlarge the trading volume of the index in the short term, let this part of the funds untie, repair the stock index shape and change market expectations. Otherwise, because the form has been destroyed, short-selling power will prevail and loose chips will continue to suppress the operation of the stock index.

2. Secondly, from the perspective of multiple groups in the market, it is impossible to rebound in large quantities, indicating that the financial strength of entering the market to grab funds is not strong or unwilling to buy in large quantities, because the limited amount of energy reflects that the scale of active buying is not very large, and long-term funds may only be the group with less resistance to pulling up or the index stocks rebound. Therefore, the shrinkage of the rebound shows that the long-term capital strength is not strong or unwilling to make great efforts to attract funds. When investors discover the real situation of the strength of bulls, they naturally lack the confidence to follow suit and add positions. The loose chips in the market will be converted into selling orders, which will easily make the weak rebound die.
