What does it mean to sell short InflaRx stock? Short selling IFRX is an investing strategy that aims to generate trading profit from InflaRx as its price is falling. IFRX shares are trading up $0.13 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. How does a short squeeze work against InflaRx? A short squeeze for InflaRx 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 IFRX, which in turn drives the price of the stock up even further. How often is InflaRx's short interest reported? Short interest is typically published by a stock exchange once per month. However, NASDAQ publishes a report for U.S. stocks, including IFRX, twice per month. The most recent reporting period available is April, 30 2025.
