A-Share Screening by Turnover, Reversal Candles, and Auction Activity

Summary

This A-share selection rule looks for stocks with turnover between 3% and 12%, a reversal-style candle pattern, and previous-session auction turnover above 0.26. The stated purpose of the auction-activity condition is to filter for names with short-term trading interest. The article includes an indicator formula and a Python illustration, alongside suggestions to consider fundamentals, industry conditions, and the broader market environment.

No historical test, return series, or benchmark comparison is offered, so the screen's effectiveness cannot be assessed from the document. Its explanation identifies sensitivity to market sentiment and the possibility of selecting actively traded stocks with weak longer-term prospects. The Python example also appears inconsistent with the described equity method: it uses futures settlement data to represent the reversal condition and a market-flow field to estimate auction turnover. Those implementation details should not be treated as a validated reproduction of the stated screen.

Key ideas

• The screen uses a turnover range, a reversal-style candle condition, and prior auction turnover.
• The auction-turnover filter is intended to capture short-term trading activity.
• The article identifies sentiment sensitivity and weak long-term fundamentals as risks.
• It suggests considering valuation, industry, and market context.
• The code illustration does not clearly implement the described equity indicators, and no performance test is provided.
