Two-way shorting of stock and foreign exchange refers to shorting the stock market and foreign exchange market of a country or region at the same time, which makes the stock market and foreign exchange market of this country or region fall and gain income. The most typical example is the Asian financial turmoil of 1998, which is a typical example of two-way short selling of stocks and foreign exchange. Hedge funds, led by Solo period, shorted the stock market and foreign exchange market in Southeast Asia in large quantities. In fact, the two-way short selling of stocks and foreign exchange appeared once in the United States before 1998, when it was also a hedge fund headed by Soros.
