Monthly Fails‑to‑Deliver Reporting

More Detailed Short‑Interest Data
FINRA filed a proposed change (May 1, 2026) to amend Rule 4560 so FINRA will collect and disseminate short‑interest information with greater frequency and more detail. The proposal was published in the Federal Register on May 18, 2026, and the SEC extended its review until August 14, 2026.
