Short selling NVAX is an investing strategy that aims to generate trading profit from Novavax as its price is falling. NVAX shares are trading down $0.04 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.
