Chinese Stock Screen Using Turnover, 龙虎榜 Activity, and Auction Price

Summary

This Chinese equity screening rule combines a turnover range of 3% to 12% with two short-term market conditions: the stock appeared on the previous day’s 龙虎榜, a public ranking of notable trading activity, and its 9:15 opening-auction matched price was at the limit-down level. The article frames the combination as a way to filter for liquidity, notable investor attention, and a potentially unusual auction signal. It gives example screening logic in indicator and Python-like form.

The text does not report a backtest, returns, or evidence that the auction condition predicts a rebound; the proposed interpretation that favorable information may have been overlooked is speculative. It warns that the screen may overfit and omits company fundamentals, earnings changes, and broader market conditions. It recommends incorporating fundamental and industry information, while offering no tested optimization. There is also an apparent mismatch between the stated limit-down condition and the sample formula’s comparison of the matched price with 90% of the close, so implementations should verify the intended definition before use.

Key ideas

• The screen requires turnover between 3% and 12% and prior-day 龙虎榜 inclusion.
• It also uses a prior-day 9:15 auction matched-price condition described as limit-down.
• The article interprets the combination as a liquidity and short-term attention filter, without presenting supporting performance evidence.
• It cautions that the rule may overfit and excludes fundamental and market-regime factors.
• The written condition and sample comparison may not express the same auction-price test.
