Undervalued Stock Screener

A stock screener built specifically for A-share markets that filters for fundamentally strong but undervalued companies. It walks you through setting parameters like market cap range and sector focus, then applies six-layer screening (PE/PB below industry median, positive revenue growth, healthy balance sheets, positive free cash flow, high ROE). What's useful here is the A-share context baked in: it accounts for non-recurring items that inflate reported earnings, explains why state-owned enterprises trade at discounts, and reminds you that Chinese markets have structurally higher PE ratios than Western ones. The methodology doc is thorough and it can integrate with real-time market data if you need it. Worth noting it explicitly states this is not investment advice, which is the right call.
