Stock Screening for Reversal Patterns After Three Limit-Up Sessions

Summary

This Chinese-language strategy note proposes screening stocks with turnover between 3% and 12%, a reversal or engulfing-style pattern, and three consecutive limit-up sessions on the prior day. It frames the combination as a way to find stocks showing strong short-term attention and potential breakout behavior. The note includes formula and Python examples intended to illustrate a screen based on market capitalization, the high-to-low range, and consecutive unchanged closes as proxies for some conditions.

The implementation details are not fully consistent with the prose: the examples do not clearly encode the stated turnover range or prior-day three-session limit-up condition, and the close comparisons may not capture the described reversal pattern. The author acknowledges sensitivity to short-term sentiment, potential selection bias, higher trading costs, and capital demands. Suggestions include adding valuation or technical filters, but no backtest or performance evidence is supplied, so the screen remains an unvalidated idea.

Key ideas

• The proposed screen combines a 3% to 12% turnover range with a reversal pattern.
• It additionally targets stocks described as having three consecutive limit-up sessions on the previous day.
• The examples use market-capitalization and daily price-range proxies, but do not clearly implement every stated condition.
• The author notes that sentiment, trading costs, and capital requirements can affect the approach.
• The document offers no evidence from historical or live performance.
