These two kinds of Shanghai and Shenzhen 300ETF are short-selling in disguised form through margin financing and securities lending, but they are still very different from short-selling stock index futures, mainly because the leverage ratio is quite different: the margin of stock index futures is generally 20%, that is, the maximum leverage is 5 times; The maximum margin financing and securities lending is only 50%, which is twice the leverage (the requirements of futures and securities companies are different, but they are roughly the same. )。 In addition, the holding time is also very different.

Shanghai and Shenzhen 300ETF can participate in trading as long as it has a Shanghai and Shenzhen stock account. Just like stocks, you can buy at least 1 lot (100 lot), and the current price is not higher than that of 300 yuan. As for shorting through securities lending, it depends on whether your brokerage firm is engaged in margin trading and whether you are qualified to open this business. Generally, you need more than tens of thousands of assets and how many years of trading. Please consult your brokerage company.
