The stock has a loss of 1 gross. As long as it does not withdraw from the market, there is still a chance to rebound. Futures are different. Futures are margin trading, with about ten times leverage. If you stop trading, most of the margin will be lost. And futures are settled on the same day. If the account funds are insufficient, the brokerage firm will force the liquidation, and the stock will not force the liquidation if it falls again! So if what he said at the beginning was speculation in futures, no one would dare to borrow it. Everyone knows the risks.
