StockCheck is an independent research tool focused on valuation percentiles and quantitative stock screening across A-shares, Hong Kong equities, and U.S. equities, built and maintained by an independent fintech team dedicated to cross-cycle quantitative fundamental research. Amid the noise and structural information asymmetry of secondary markets, we hold to understanding markets through objective data rather than sentiment — that's the core of our quantitative analysis philosophy.
StockCheck is powered by continuously refreshed fundamental databases covering A-shares, Hong Kong equities, and U.S. equities. Through a fully white-boxed, transparent, and reproducible layer of mathematical formulas, we distill dense corporate filings and market data into core quantitative factors — historical percentile rankings for P/E, P/B, dividend yield and more, looking back as far as 20 years of history — so you can tell in seconds whether a stock or index currently sits in undervalued, fair, or overvalued territory.
StockCheck was founded by a senior investment research team rooted in the Greater China capital markets. Core members bring over 15 years of securities market research and hands-on experience across both value investing and quantitative investing — the practical foundation behind the site's methodology of objective, data-driven analysis and multi-period historical percentile quantification. To be clear, StockCheck is a data and tooling product, not a securities investment advisory firm; this background is shared only to illustrate the expertise behind our percentile methodology, and does not represent any promise or guarantee — by the site or any team member — regarding the future performance of any specific security.
StockCheck currently covers mainland China A-shares, Hong Kong main-board listings and major indices, and U.S. equities listed on the NYSE and NASDAQ along with their major indices. It's an independent research tool built for cross-market quantitative valuation and stock screening, and is not affiliated with any brokerage or investment advisory firm.
Every valuation percentile is computed on a rolling basis over a long lookback window — 3, 5, 10, and up to 20 years — of historical data. Nothing is based on subjective forecasts or manual ratings — the same calculation logic applies transparently and consistently to every user, reflecting our commitment to objective data and quantitative analysis.
To close the information gap between institutions and everyday investors, using rigorous statistical methods to help every independent-minded investor build their own, fully auditable valuation framework.
