Chinese Stock Screen Using Volatility, Turnover, and a Limit-Down Auction Price

Summary

This Chinese equity screening idea combines three conditions: price amplitude above 1, previous-day turnover value above 60 million, and a previous-day 9:15 matched auction price at the down-limit. The accompanying explanation treats amplitude and turnover as proxies for volatility and liquidity, and the limit-down condition as a way to find stocks that might rebound. The article also includes a sample implementation, though its calculations do not clearly match every stated condition.

The document provides no backtest, performance figures, or evidence that the screen predicts rebounds. It cautions that the approach depends heavily on recent price action, omits company and industry fundamentals, and may exclude stocks that later perform well. It is presented as a limited-use selection rule rather than a long-term strategy; suggested refinements include adding fundamental and broader market factors and revisiting the thresholds.

Key ideas

• The screen combines an amplitude threshold, a previous-day turnover-value threshold, and a previous-day 9:15 auction-price limit-down condition.
• The rationale is to target liquid, volatile shares that may have rebound potential after a sharp decline.
• The article gives no historical test or evidence of profitability.
• The rule omits fundamentals and may be unsuitable for long-term investing.
