Stock Screening by Capital Strength and Opening Gain, with Valuation Filters

Summary

This Chinese stock-screening post proposes ranking shares by capital-flow strength and requiring the 9:25 opening gain to be below 6%. Its revised screening logic adds a top-100 capital-strength ranking, a price-to-earnings ratio below 20, a price-to-book ratio below 1, and a five-year history. The post initially refers to 2021, then recommends using a longer time range.

The rationale is that strong inflows may signal market interest, while a modest opening gain could leave room for appreciation. The post supplies no backtest results or performance evidence. It cautions that capital-flow measures can lose relevance as market conditions change, opening gains are hard to predict, and a narrow sample period can miss longer-term winners. It suggests adding sentiment and other indicators, but offers no validation showing that the proposed filters improve returns.

Key ideas

• The screen ranks stocks by capital strength and limits the 9:25 opening gain to below 6%.
• The revised version adds top-100 capital strength, valuation thresholds, and a five-year data window.
• The post treats capital inflows as a possible sign of market interest, not as a proven predictor.
• It provides no performance results and flags changing flows, uncertain opening moves, and limited history as risks.
