The United States is the world’s largest stock market with the highest degree of freedom, transparency and huge liquidity. Foreign investors who comply with the reporting system are not required to pay profits tax. In addition, the trading hours of the U.S. stock market are from 10:30 pm to 5 am Hong Kong time, while the summer trading hours are from 9:30 pm to 4 am Hong Kong time. Therefore, investors can take advantage of the time difference to fully participate in and keep up with the trend of the US stock market. The main trading markets for U.S. stocks: New York Stock Exchange (New York Stock Exchange), American Stock Exchange (American Stock Exchange), over-the-counter (OTC) and Nasdaq.

There are several ways to short U.S. stocks.

Method 1 is to short the stock directly. For example, Yahoo's stock YHOO. You can first borrow stocks from a brokerage and sell them. When Yahoo falls, buy back the shares and return them to the brokerage. Earn the difference. This is the exact opposite of going long.

Method 2, there are many companies in the US stock market with corresponding options (Options). Options expire in one month, two months, one year, etc. There is also a price difference. For example, Yahoo has options with an underlying price of 10 yuan, 15 yuan, etc. Relative to the expiration time, the underlying price, there are long (CALL) and short (PUT). If you have stocks in hand, you can sell options to others (this is a bit like "issuing" options yourself). This is called a "write" operation (WRITE). So if you go short, you have two options.

1. Directly buying short options (buying PUT) requires less investment.

2. After buying the stock, "write" the long option to others. Regardless of whether the stock rises or falls, as long as the underlying price is above the current price, a long option is written. There is almost nothing that is not profitable.

Method 3, in the U.S. stock market, the Dow Jones Index, S&P 500 Index, and S&P 100 Index. Every index has options. Options operations are the same as stock options. But individuals cannot do the "write" operation. To be bearish on the stock market, you can buy short options (PUT).

Method 4, there are now short-selling ETFs in the U.S. stock market. For example, short the Dow Jones Index (DXD), short the Nasdaq ETF (QID), short the Financial Services Index ETF (SKF), etc., there are more and more tricks. If you don’t want to take too much short-selling risk, the benefits of investing in this type of ETF can be considerable. Because ETFs are operated by experts.

Method 5. Futures trading. Futures trading is separate from the stock market. The main one is the Chicago Board of Trade. Stock index futures have fewer options than options. Generally, few people do stock index futures.
