Chinese Stock Screen Using Volatility, Recent Price Surges, and Price Level

Summary

This Chinese-language post outlines a stock screen combining a large daily trading range, at least one strong single-day gain within a recent 25-session window, and a specified share-price level. It also sketches formula and Python implementations, though the displayed conditions contain placeholders and inconsistencies, including a mismatch between the stated price level and the example value.

The post cautions that short-term price behavior and an exact price threshold do not establish company quality or value, and that broad market conditions and fundamentals are omitted. It suggests comparing price with historical averages, adding financial measures such as valuation and return on equity, and using a tolerance mechanism. No backtest results or evidence of predictive performance are provided, so the screen is a rough selection concept rather than a validated strategy.

Key ideas

• The screen combines a wide daily price range with a large one-day gain in a recent trading window and a price-level filter.
• The text presents code sketches, but some conditions are placeholders or inconsistent with the written description.
• An exact share-price cutoff may select stocks for an arbitrary characteristic rather than investment quality.
• The post recommends adding market context, fundamental measures, and tolerances to the screening rules.
• No performance evidence is supplied.
