Alpha-Investor 13F signals

Quarter 31-DEC-2025 → 31-MAR-2026 · 103 filers · generated 2026-07-20

Each row is a tracked 13F filer and their biggest new bet this quarter. A ⭐ star marks a high-conviction priority name we actively track — un-starred rows are concentrated, cloneable-looking books we auto-discovered, and the priority only checkbox hides those to leave just the starred managers. 13FScore (0–100) is a backtest of that filer's skill: how cloning their disclosed top holdings would have performed vs the S&P 500 — higher = more alpha and more consistent quarters (blank = too little price-covered history to score). It's marked to the latest close daily, so it drifts with the market. Sector is the category of their top new buy; use the sector dropdowns to filter. The $ticker opens that stock's detail page here; the company name opens its Google Finance page; the filer opens their page — all in a new tab, so your filters stay put. Tags flag memberships — NASDAQ, S&P 500, Citrini long, Serenity bullish, and Bitget (available to trade as a Bitget stock perpetual) — refreshed daily. Click any column header to sort.
