Short selling refers to an investor selling existing securities because he expects the market price to fall. At this time, the way to make money is to sell it at a higher price first, and then buy it back at a lower price to get the difference. This is the classic short-selling investment strategy.
The biggest feature of the above two methods is that they can only make money after the market falls, and this method of making money is often attributed to the unsuccessful market investment method, which provides a channel for those who want to make short investments to obtain income. But it should be noted that any stock investment has great risks, so don't try it easily.
