Short selling INSM is an investing strategy that aims to generate trading profit from Insmed as its price is falling. INSM shares are trading down $0.24 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.
