Fluctuation is the most basic direction of asset price movement. When the target asset goes up, we can get the spread income through multiple orders, and when the target asset goes down, we can get the spread income through short orders. So what does the short list mean?

What do you mean by an empty bill?

Short selling is short selling, which is an operation mode that brings benefits through falling asset prices. In the stock market, investors' short selling behavior is a way to borrow shares first, then sell them, then buy them back at a low price when the stock price falls, and then return them to the borrower. Among them, because the share price when the stock is returned is lower than the share price when it is lent, investors can get income.

For example, if you borrow 10 yuan's stock, you will get 10 yuan's profit after you sell it, and then buy it back when the stock price falls to 8 yuan, so you will get 2 yuan's profit.

How can I short? Some markets can be short directly, such as futures market, and some markets need to open related businesses, such as stock market. In China, it is necessary to open margin trading in securities companies to short stocks.
