Short selling PCAR is an investing strategy that aims to generate trading profit from PACCAR as its price is falling. PCAR shares are trading up $1.80 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.
