Screening Main-Board Stocks by Turnover, Daily Gains, and Afternoon Flows

Summary

The document describes a short-horizon Chinese stock screen requiring turnover between 3% and 12%, a daily gain above 1%, main-board status, non-ST classification, and positive large-order net inflows during the afternoon. Its accompanying indicator logic also refers to moving averages, volume relative to recent averages, listing age, and exclusion of limit-up stocks, so the implementation includes conditions beyond the summary screen.

The post characterizes turnover and price change as signs of activity and strength, with afternoon large-order flows used as a capital-flow signal. It cautions that the approach uses a short time frame and omits company fundamentals, so it may miss broader valuation and market risks. The sample code and rules are illustrative only: no historical test, performance measure, or evidence of predictive value is supplied, and the written criteria do not align perfectly with every implementation detail.

Key ideas

• The stated screen combines a turnover band, a positive daily price move, main-board eligibility, and positive afternoon large-order flows.
• The indicator example adds moving-average, volume, and listing-age conditions.
• The approach uses short-term trading activity and capital flows without a full fundamental assessment.
• The document supplies no backtest or performance evidence, and its implementation details differ from the prose.
