Chinese Stock Screen Using Amplitude, Share Control, and Valuation

Summary

This Chinese equity screening example selects stocks using daily amplitude, a measure labeled today's controlling share change, and circulating market capitalization. It then expands the screen with positive price-to-earnings below a stated ceiling and a closing price above its 20-day moving average. The article includes example implementations in a stock-screening platform and Python, and describes ranking the selected names by market capitalization before returning a limited list.

The author notes that market capitalization alone does not measure company value and that the initial criteria omit other fundamentals. Suggested additions include valuation measures and technical indicators; the final example incorporates price-to-earnings and a moving-average filter. No backtest results, transaction costs, sample period, or risk-adjusted performance are supplied. The share-control field and thresholds are not defined in depth, and the code is presented as a reference requiring adaptation. The screen is therefore a set of illustrative selection rules, not evidence that the resulting portfolio will outperform.

Key ideas

• The screen combines stock amplitude, a controlling-share measure, and circulating market capitalization.
• The expanded rules add a positive, capped price-to-earnings ratio and a close above its 20-day average.
• The example ranks selected stocks by market capitalization and limits the returned list.
• The article flags incomplete fundamentals and provides no backtest or performance evidence.
