Short selling WDC is an investing strategy that aims to generate trading profit from Western Digital as its price is falling. WDC shares are trading down $0.28 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.

A short squeeze for Western Digital occurs when it has a large amount of short interest and its stock increases in price. This forces short sellers to cover their short interest positions by buying actual shares of WDC, which in turn drives the price of the stock up even further.
