Chinese Stock Screen Using Price Amplitude and a New Low Condition

Summary

This Chinese stock-selection proposal uses price amplitude above a threshold, excludes Beijing-listed shares, and compares the current day's low with the previous day's low. It presents the screen as a simple way to identify shares with notable price movement, then suggests expanding it with market capitalization, technical measures, company fundamentals, industry information, and explicit risk controls. A Python example also shows filtering by amplitude and region before sorting candidates by circulating market value.

The document supplies no historical test or evidence that the conditions predict returns. It warns that the screen omits other indicators and fundamental quality, leaving it exposed to one-off events and weak companies. There is also an inconsistency in the stated rule: the prose calls for today's low to be below yesterday's, while the formula and Python condition use a greater-than-or-equal comparison. That mismatch should be resolved before implementation; as written, the examples do not encode the described lower-low rule.

Key ideas

• The proposed screen combines price amplitude, a regional exclusion, and a comparison of daily lows.
• The Python example sorts qualifying shares by circulating market value.
• The document suggests adding technical, fundamental, and industry information.
• No backtest or evidence of predictive performance is provided.
• The prose specifies a lower current low, but the code uses a greater-than-or-equal condition.
