How current is this institutional ownership data?

This reflects the Mar 31, 2026 13F filing cycle. Institutional investors have up to 45 days after quarter-end to file, so this data can lag real-time positioning by 1-3 months, and only U.S.-registered institutional managers above the SEC's reporting threshold are required to file at all.

Sourced from SEC 13F filings for CORT. This table holds one snapshot per institution, not a multi-quarter history, so no ownership trend over years, historical percentile, or fund track record is shown, since that data is not available here. Only U.S.-registered institutional investment managers above the SEC's reporting threshold are required to file 13Fs; hedge funds, foreign investors, and smaller managers may not appear.
