However, some varieties are big contracts as soon as they are listed, which ordinary investors can't afford, and enterprises dare not hedge rashly because of insufficient liquidity. If it lacks liquidity, it will not achieve the expected hedging purpose. In addition, some varieties of enterprises simply don't want to hedge. This is my guess, because such enterprises have no intention of avoiding risks at all, but only hold price increase meetings and raise prices, and have no motivation to do things to improve efficiency.
If some varieties are lifeless, there must be internal reasons. Some stocks in the stock market are dead, which theoretically shows that he is not favored by investors for the time being, so he will try to improve and get more investment. However, these are all appearances and need to be analyzed in detail.
