Selecting Chinese Stocks by Range, Rising Averages, and Relative Volume

Summary

The article outlines a stock screen requiring daily price amplitude above 1, upward-moving averages, and a volume ratio between 1.5 and 6. It defines the volume ratio as current-day trading volume relative to the prior five-day average, using it to seek active stocks that also show an upward price tendency. The headline mentions a lower threshold above 1, while the strategy description and final rule specify above 1.5.

The text includes example formula and Python references, but their calculations and conditions do not align cleanly with the prose. It gives no backtest results or evidence that the screen predicts future returns. The author notes that the rules omit company fundamentals and that trading activity may not persist, then suggests adding measures such as earnings, valuation, dividends, or RSI and evaluating more stable volume-ratio thresholds. The screen is presented as a selection rule, not a complete portfolio or execution plan.

Key ideas

• The screen combines price amplitude, rising moving averages, and a bounded volume ratio.
• The written final rule sets the volume ratio above 1.5 and below 6, despite the headline’s lower threshold.
• The volume ratio is described as current volume divided by its prior five-day average.
• The article notes that the screen omits fundamental factors and cannot ensure future activity.
• No performance test or predictive evidence is reported, and the code examples may not match the prose exactly.
