Short selling CLS is an investing strategy that aims to generate trading profit from Celestica as its price is falling. CLS shares are trading up $1.08 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.

How does a short squeeze work against Celestica? A short squeeze for Celestica 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 CLS, which in turn drives the price of the stock up even further.
