This figure is short-sale volume, a daily FINRA Reg SHO trading-flow statistic, not the bi-monthly reported short interest position. See short interest vs short-sale volume for why the two numbers cannot be substituted for each other. Days to cover compares a reported short position with average daily volume; read what days to cover does and does not tell you before using this figure that way. Short interest itself is only published after a settlement-date lag; see FINRA short interest settlement dates in 2026 for the current schedule and why the gap matters. Nothing on this page predicts a squeeze or estimates a probability of one occurring; it reports one observed trading-flow ratio for one session.
