Who holds a stock and how, measured across every 13F filer's book for the newest closed quarter, with the quarter before for trends: conviction, crowding (high-turnover filers and private-fund advisers as a fraction of shares outstanding, with its percentile), ownership of the estimated free float, holder concentration, how long holders have held it, the holders' estimated average cost per share and the value held at an estimated loss, active holders' like-for-like change, top-scored managers' net buying, Schedule 13D and 13G stakes on record, the holder-overlap peers and the filers with the highest weight in the stock. Cost figures are estimates from quarter average prices, never filed. Ratios are fractions.

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.

One listing's holder signals at a closed 13F quarter, measured across every 13F filer's book. Ratios are fractions (0.25 is 25%); null means not measurable, never zero. Share counts are as filed for the quarter.
