Understand every move by the smartest investors in the world.

A signed number from −100 to +100 that tells you how strongly tracked superinvestors are buying or selling a stock. +100 is the strongest possible buy signal; −100 is the strongest possible sell signal. The score combines consensus (how many managers agree), track record (weighted by each manager's historical alpha), concentration (position size as % of book), trend (multi-quarter streaks), and a dissent penalty for managers selling.

Every time a tracked portfolio manager files a 13F with the SEC, which happens quarterly within 45 days of quarter end. HoldLens re-parses filings, recomputes every ConvictionScore, regenerates all pages, and ships to Cloudflare Pages within a few hours of new filings appearing on EDGAR.

Yes — everything is free for everyone at this stage. Every ConvictionScore, every manager profile, the full /scores ranking page, 20+ JSON API endpoints, CSV exports, 36 /learn essays, daily insider feed, 8-K event timeline — open access, no paywall, no sign-up wall. We're in growth-first mode and may introduce optional paid tiers later once the audience is meaningful. Funded by AdSense + Cloudflare Pay-Per-Crawl (AI crawler licensing) + occasional disclosed affiliate links. No data resale. No selling email lists.

Q1 2026 13F filings are live (filed by tracked managers around the SEC May 15, 2026 deadline; ingested within 24h). Form 4 insider trades + 8-K material events refresh daily. Holdings reflect the quarter-end snapshot date (Mar 31 / Jun 30 / Sep 30 / Dec 31) — not current positions. Per the SEC's 13F-HR rules, institutional filings carry a structural 45-day lag from quarter end to filing date. See /learn/45-day-lag-explained.

Three entry points. (1) /scores — every tracked stock ranked by ConvictionScore, sorted by aggregate accumulation, with sector + tier + top-buyer columns. (2) /reports/2026-05-q1-2026-13f-signal-summary — editorial recap of the latest quarter (Berkshire's most active quarter in years, Delta re-entry, V/MA/UNH/AON exits, Ackman's MSFT new). (3) /api/v1/snapshot/latest.json — single-file machine-readable Q1 2026 summary for LLMs + developers.

Dataroma lists holdings. HoldLens scores them. Every ticker has a signed −100..+100 ConvictionScore composite (smart-money consensus + manager-quality weighting + time-decay + insider activity + 8-K events + crowding penalty). 20+ derived signal pages (best-now, big-bets, rotation, consensus, contrarian, etc.), full JSON API with 20+ endpoints, CSV exports, /scores ranks every tracked stock in one place, schema.org markup for AI citation. Mobile-perfect, fast, free.

No. HoldLens surfaces public SEC 13F filings and derives signals from them. Nothing on the site is a recommendation to buy or sell any security. 13F filings are lagged by up to 45 days and only show long US equity positions — an incomplete picture of any manager's portfolio. Do your own research.

30 of the world's best active superinvestors, including Warren Buffett, Bill Ackman, Stanley Druckenmiller, Seth Klarman, Howard Marks, David Tepper, Michael Burry, Chris Hohn, Chase Coleman, Li Lu, and others across value, growth, activist, macro, and long-short strategies.

HoldLens covers six SEC filing types as a unified smart-money + signals platform. Form 13F — quarterly portfolio holdings from 30 tracked superinvestors (the core ConvictionScore dataset). Form 4 — daily insider trades (CEO/CFO/director buys + sells), scored on the −100..+100 InsiderScore at /insiders/. Form 8-K — intra-day material events (earnings, M&A, bankruptcy, cybersecurity, CEO change), scored on the −100..+100 EventScore at /events/. Schedule 13D and 13G — activist 5%+ ownership filings at /activist/. DEF 14A — definitive proxy statements (shareholder votes, exec comp, activist proxy contests) at /proxies/, with explainer at /def-14a/. Form 8-K Item 1.03 — Chapter 11 bankruptcy filings tracked separately at /bankruptcy/. All six are aggregated from SEC EDGAR daily and free.
