The Need for Real-Time Short Data
Official US short interest data, published by FINRA, is notoriously stale, arriving twice a month with an 8-11 day lag. Ortex addresses this information asymmetry by providing daily and intraday short interest estimates for over 15,800 US securities. By modeling securities-lending data, Ortex offers a more current view of short positioning, including cost-to-borrow, utilization, and days-to-cover.
Why It Matters
For traders and risk managers, relying solely on official prints can lead to significant blind spots. Ortex's ability to track short interest as it builds throughout the session allows for better monitoring of potential short squeeze setups. With 95% of estimates falling within one percentage point of official prints, this data serves as a critical tool for identifying shifts in market sentiment before they are reflected in official exchange reports.
