Screening Stocks by Opening Gain, Daily Range, and Market Capitalization

Summary

This Chinese stock screen selects shares whose daily high-to-low range exceeds one percent, market capitalization is above 200 million, and the reported gain around the 9:25 pre-open observation is below six percent. The proposed rationale is to focus on relatively active, larger stocks while avoiding names that have already risen sharply in the short term. The post presents the criteria as potentially relevant to short-term or intraday trading.

The article acknowledges that high price variation exposes traders to market risk, that market capitalization and opening movement do not capture company fundamentals, and that using one observation time may miss opportunities. It recommends combining the conditions with fundamental or technical factors, but supplies no backtest or evidence that the screen improves returns. Its sample formulas also use opening-price fields, leaving some ambiguity about how the 9:25 condition is measured in practice.

Key ideas

• The screen requires a daily high-low range above one percent and market capitalization above 200 million.
• It excludes stocks with a reported 9:25 gain of six percent or more.
• The rationale is to find active, larger stocks without an already large short-term rise.
• The post notes market risk and missing fundamental information, with no reported performance evidence.
