Screening Mainboard Stocks by Turnover, Daily Gains, and Prior Opening Match

Summary

This post describes a Chinese-market stock screen that selects mainboard shares with turnover between 3% and 12%, a daily gain above 1%, and a previous-day 9:15 matched price at the limit down. Its rationale is that moderate turnover and positive current performance may indicate market interest, while the prior opening-price event could point to a short-term rebound opportunity. The post offers no backtest, performance figures, or details about execution, so the proposed edge is not demonstrated.

The author flags that the screen ignores company fundamentals and relies on a narrow set of trading and price conditions. It also notes that the single prior-day price observation may miss other relevant price behavior. Suggested refinements include incorporating company, sector, and trading-related factors, and using a broader time window or additional market indicators. The post is therefore a screening idea rather than a complete trading strategy: it does not specify position sizing, exit rules, or how to handle risk.

Key ideas

• The screen requires mainboard status, turnover between 3% and 12%, and a daily gain above 1%.\nIt also selects stocks whose previous-day 9:15 matched price was at the limit down.\nThe author suggests the combination may identify a short-term rebound opportunity, but supplies no performance evidence.\nThe screen omits fundamentals and may overlook price behavior beyond the specified observation.\nPotential refinements include adding company and sector information or broader market indicators.
