What does it mean to sell short Microsoft stock? Short selling MSFT is an investing strategy that aims to generate trading profit from Microsoft as its price is falling. MSFT shares are trading down $0.52 today. To short a stock, an investor borrows shares, sells them and buys the shares back on the public market later to return it to the lender. Short sellers are betting that a stock will decline in price. If the stock does drop after selling, the short seller buys it back at a lower price and returns it to the lender. The difference between the sell price and the buy price is the trader's profit. How does a short squeeze work against Microsoft?
