Three things this tool does differently
It tells you how old the number is.Short interest is a twice-monthly snapshot, never a live figure, and the freshest datapoint available anywhere cycles between roughly nine and twenty-six days old. Several popular tools display it beside a live-updating price with no date attached, which invites you to read a three-week-old position as today’s. Every page here leads with the settlement date, the age in days, and when the next cycle is expected.
It will not show percent of float. That is the headline metric across this category and it cannot be computed honestly from free data, because no free source publishes a float share count. What free sites label float is either shares outstanding renamed or a licensed commercial estimate. We publish percent of shares outstanding, from filings, and say which one it is.
Days to cover is FINRA’s own. FINRA computes it at each settlement and we pass it through. Tools that compute their own divide by a volume window they choose and generally do not disclose, which is why the same stock can show noticeably different days-to-cover figures depending on where you look.
Short interest is not short volume
These get conflated constantly. Short interest is the number of shares currently held short, reported twice a month. Short volume is how many shares traded on a given day were sell-short orders, published daily. A high daily short volume does not mean a large short position, because most of it is market makers hedging and closing within the session. This tool shows short interest.
