longbridge-graham-screener

Prompt-only batch screener. Given a market or index universe, applies Graham's six hard filters (NCAV, PE, PB, dividend yield, debt coverage, earnings stability), scores each name on a 100-point static + dynamic composite, and returns a ranked list of stocks meeting Graham's quantitative criteria, with Graham buy lines, holding-period expectation, and value-trap warnings.

For single-stock deep diagnostic use longbridge-graham-stock-analysis. For broader low-PE / low-PB / high-ROE value (not NCAV-centric) use longbridge-value-screen. For high-dividend-only screens use longbridge-dividend-screen.

Cognitive frame (do not skip)

Graham screening is patient arbitrage, not a dip-buy signal. Hold periods: 6–18 months (explicit catalyst), 1–3 years (sector re-rating), 3–5 years (organic accrual), or never (value trap — exit). Every ranking output must carry the waiting-cost (dividend yield) and the holding-period framing; never display a score number on its own.
