Short selling of stock index futures is allowed, but the relevant rules require a certain margin requirement as a guarantee for trading. In fact, it is not completely naked short selling. This kind of short selling in the futures market is called short selling.

In addition, naked short selling is mainly aimed at stocks. At present, the relevant trading rules of margin financing and securities lending show that it is not naked short selling, because securities lending needs to borrow stocks from brokers and other institutions to sell short, which is actually not naked short selling. Naked short selling is actually a short selling behavior of such stocks without such stocks.

For naked short selling, there are certain trading restrictions in mature international stock markets, which cannot be implemented casually. For China, a developing stock market, this behavior should be implemented step by step. You can take a look and say that stock index futures and margin financing and securities lending have been implemented for at least one year.
