Percentiles describe where a figure sits among industry peers reporting it (100th = highest). They are position within a peer group, not a rating, and not investment advice. Short interest ranking uses days to cover from FINRA Consolidated Short Interest data; FINRA is the owner and source of that data, included at no additional charge.

Institutional ownership

Held by 3 of the superinvestors we track (plus 7 quant / multi-strat books), based on each investor’s most recent 13F (latest Q1 2026).

From quarterly Form 13F filings, which can be up to 45 days delayed. Long US-listed positions only: excludes short positions, options, cash, bonds, and non-US holdings, so this is not a manager’s complete portfolio. Counts are of the investors we track, not all institutions. Not investment advice.

Recent insider activity

Reported non-derivative purchases and sales (codes P/S) — which may be open-market or private; excludes option exercises, grants, and shares withheld for taxes.

Not investment advice.
