StoneRecord collects the holdings, letters and earnings calls of top overseas value investors and turns them into plain Chinese (and English) summaries. This page helps you get started — no deep investing background needed.
Try this: (1) open the Ranking on the Signal Graph and pick a "strongest signal" — a stock the most mutually-independent managers are bullish on; (2) tap it to see what each manager says and how management framed the latest results; (3) for depth, read the full deep-read.
Open the Signal Graph →Currently 9 value-investing "letter writers" (Marathon, Hosking, TCI, and others). On any card or article, the ⓘ next to an institution name shows who founded it and its style.
Browse all their research →13F: a U.S. SEC filing that managers overseeing more than $100M must submit each quarter, disclosing their U.S. stock holdings — how we track what institutions are buying and selling.
Convergence: multiple mutually-independent top managers landing on the same theme/company — the more they converge, the more likely it is a real signal rather than noise.
Signal score: how many mutually-independent top managers are bullish at once — public praise in letters, real-money 13F holdings and 13D activist stakes all add to it, with "said it AND did it" cross-confirmation scoring highest. Higher score, stronger signal.
Triangulation: a company that is both bullish in managers' letters and backed with real money — held in 13F or targeted by a 13D stake — "what they say" and "what they do" cross-confirm each other, the strongest signal.
Earnings call: the quarterly call a company holds with analysts after reporting results, where management walks through the numbers and takes questions.
Holdings from SEC EDGAR 13F filings, letters from each firm's own site, earnings-call notes from Motley Fool — all auto-translated and refreshed weekly.
The site updates automatically every Monday (new research, 13F holdings, the signal graph). Two ways to keep up: (1) RSS — subscribe with any reader (Follow / Feedly / NetNewsWire), one feed for research and one for 13D/G signals; (2) RedNote — weekly picks are posted on the official account.
StoneRecord is an independent personal project, built by an individual investor with years of overseas-market research experience. It grew out of a belief in long-termism: reading primary sources and learning from genuinely patient capital beats chasing market noise — and language should not stand between readers and the world's best investment thinking.
