Short selling NI is an investing strategy that aims to generate trading profit from NiSource as its price is falling. NI shares are trading up $0.61 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.
