What does it mean to sell short Cerus stock? Short selling CERS is an investing strategy that aims to generate trading profit from Cerus as its price is falling. 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 Cerus? A short squeeze for Cerus occurs when it has a large amount of short interest and its stock appreciates in price. This forces short sellers to cover their short interest positions by buying actual shares of CERS, which in turn drives the price of the stock up even further. How often is Cerus' 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 CERS, twice per month. The most recent reporting period available is November, 30 2024.
