Although short positions are a way to show bearish expectations, it should be noted that each market situation is different. The market has different reactions to the negative situation of the market, so the risks brought by short positions will also change. The risk of short positions is an overreaction caused by investors' bearish sentiment, which may make investors sell their own stocks or futures contracts in the market without restraint. This situation will aggravate market volatility and may lead to greater market trends. Therefore, when taking short positions, it is necessary to carefully consider the market situation and investors' reaction to the market bearish situation in order to effectively manage risks.
