Chinese Stock Screening with Weekly Moving-Average Crossovers and Limit-Down Pricing

Summary

This Chinese stock selection approach combines three conditions: daily amplitude above a stated threshold, a weekly five-period moving average crossing above the ten-period average, and a prior-day 9:15 matched price at the down-limit level. The stated rationale is to find volatile stocks whose weekly trend appears to be improving after a sharply weak opening indication. The document also gives formulas for amplitude and moving averages, plus a Python example that sketches how to screen listed stocks with market data.

The article presents no performance results or validation for the combined filter. Its code example has apparent implementation gaps, including a matched-price field not retrieved in the shown data request and a condition that may not evaluate as intended for a time series. It also acknowledges that the screen omits fundamentals and broader market conditions, and that high-amplitude stocks can carry elevated risk. The method is therefore a screening hypothesis, not evidence of an established return advantage.

Key ideas

• The screen combines daily price amplitude, a weekly moving-average crossover, and a prior-day matched-price condition.
• It aims to identify volatile stocks with a potentially improving medium-term trend.
• The article provides formulas and a sample screening outline but no evidence of historical performance.
• The selection omits fundamental and broad-market information, and volatile candidates may carry greater risk.
