Short selling SIRI is an investing strategy that aims to generate trading profit from Sirius XM 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 Sirius XM? A short squeeze for Sirius XM occurs when it has a large amount of short interest and its stock appreciates in price.

How often is Sirius XM'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 SIRI, twice per month. The most recent reporting period available is September, 30 2026. What do SIRI's short interest metrics mean?
