The curated superinvestor directory — well-known value investors and fund managers, each with their 13F filer CIK, latest published tracked portfolio value, position count, quarter-over-quarter change, and report date. Values normally use report-date closing prices, may fall back to filer values, and can be zero when unavailable. Use the CIK with the institution endpoints for a manager's full holdings.

What happened to a requested ticker that no longer trades. "delisted": the company has no current US listing, so the answer is its history. "renamed": the company now trades as successorTicker, its current US presentation ticker (possibly another share class). A listed series (short volume, short interest, off-exchange volume, fails-to-deliver, congressional trades) is the retired ticker's own; a company-level read is the company's data.
