Data verified 2026-08-14 · sourced from SEC EDGAR

Informational only — not investment advice. HoldLens tracks institutional positioning from public 13F filings. We are not a registered investment advisor and do not provide recommendations to buy or sell securities. Our 2026 backtest over 221 ticker-quarter pairs found the ConvictionScore has no predictive signal for forward returns (Pearson r = −0.12). The rankings describe what tracked superinvestors were accumulating or selling at the latest 13F snapshot — useful as market intelligence, not as personal investment advice. 13F data is reported with a 45-day SEC filing lag.

How to read: Size bucket from current 13F-filed portfolio weight. Trend bucket from the last 2 quarters of move activity (net delta >5% in either direction = building/trimming; new = first-appearance this quarter; exit pending = trimmed >50% last quarter). Data lag: SEC 13F filings are reported 45 days after quarter-end. This is descriptive intelligence — not investment advice.
