1, is the US stock market a t+0 transaction?
The United States is a t+0 transaction, that is, investors can open short positions or long positions at any current price, and then trade.

(1) Brokers borrow securities to sell US stocks: that is, borrow a stock from a broker, then sell the stock, buy it after the stock price falls, and then return the stock to the broker. Because the buying price at the time of closing the position is lower than the selling price at the time of opening the position, investors earn the spread income through securities lending.
② Buying and selling stock options: As a developed capital market, many stocks in the United States have options, so you can buy put options to short. Put option is the right to sell assets at a pre-agreed price. As long as the asset price is lower than the sum of the agreed price and commission, profits can be made.
(3) Buying and selling stock index options: Nasdaq, Standard & Poor's and Dow Jones, the three major American stock indexes, all have corresponding stock index options. Investors can short by buying related put options, and the profit mechanism is the same as above.
④ Shorting stock index futures: All three major indexes in the United States have corresponding stock index futures, so it is more convenient to short through stock index futures.
