The reported change is FINRA source data as of a DELAYED, roughly bi-monthly settlement — not real-time and NOT a short-squeeze prediction. It measures the change in reported short interest between two settlements, nothing more.
Data: SEC EDGAR (Form 3/4/5, 10-K/10-Q filings), the U.S. House Clerk (PTR disclosures), FINRA (short interest), and Finnhub/Yahoo (delayed daily-close prices & analyst consensus). Every figure carries its as-of date on the company page; a company with no data for this signal is excluded, never estimated.
Signal data as of 2026-06-30 — this page's date reflects the source's own reporting date, not when it was rendered.
Informational only — NOT financial advice. Every signal here is disclosed or delayed data, shown with its source and as-of date — not a prediction, ranking of quality, or recommendation.
