Chinese Stock Screening with Turnover, Capitalization, Valuation, and Price Strength

Summary

This post proposes screening Chinese stocks with a mix of recent trading activity, historical limit-up behavior, and fundamental filters. Its initial rules use today’s increase in position share above 5%, prior-day actual turnover between 3 and 28, and at least two limit-up days within 500 days. An expanded set adds market capitalization above 10 billion, price-to-earnings below 30, and a five-day gain above 10%. The explanation treats position-share increase as a proxy for buying interest, turnover as activity, and repeated limit-up moves as a sign of short-term price strength.

The author warns that the indicators can lag and that abrupt price moves may make selected stocks unsuitable by the time they are acted on. Suggested refinements include adjusting thresholds and adding filters such as size and valuation. The page includes a code fragment, but it is truncated and does not faithfully demonstrate all of the stated rules. It supplies no backtest results or evidence that the screening criteria predict future returns, so the proposal should be read as a heuristic selection recipe rather than a validated strategy.

Key ideas

• The proposed screen combines position-share increase, prior-day turnover, and repeated limit-up days.
• An expanded version adds market-capitalization, valuation, and recent-return conditions.
• The post interprets the rules as proxies for buying interest, activity, and short-term price strength.
• The author cautions that the signals may lag and may not match conditions when a trade is placed.
• The accompanying code is incomplete, and no performance evidence is provided.
