The Short Squeeze28 Aug 2019 20:07
In a short sale, an investor borrows stock from a broker and sells those shares into the market with the understanding that the shares must be bought back at a future date and returned to the broker.
If the stock falls, the investor buys back the stock at a cheaper price, making money on the trade. If the stock rises, the investor has two choices: Wait for the stock to come back down, leaving the short-seller exposed to potentially greater losses, or buy it back and realize a loss.
