In The 5th Wave's operation, many weak hedge funds will also misjudge and take the initiative to short. When most short-selling institutions in the early stage of the Five Waves concentrated on opening positions at the end of the Five Waves operation, the whole medium-term bull market often ended. The main force of hedge funds has basically realized the long-term profit of the market. In the error correction explosion of other institutions at the end of the Fifth Wave, the main funds also "surrendered" to the bulls, and to a certain extent, the purpose of cashing in a large part of the high position was achieved.
