Chinese Stock Screening by Amplitude, Main-Player Control, and Turnover

Summary

This Chinese equity screening note selects stocks with an amplitude above 1, prior-day main-player control, and prior-day turnover above 60 million. It presents the screen as a way to focus on volatile stocks and market themes, then offers sample filters and implementation guidance. The accompanying code adds several conditions, including positive valuation measures, a minimum turnover ratio, and exclusions for special-treatment stocks, so its implementation does not exactly match the stated screen.

The note gives no backtest, performance figures, or evidence that the criteria predict returns. It warns that volatility and market attention can shift with sentiment and capital flows, and that omitting fundamentals leaves the selection incomplete. It suggests adding technical, financial, and sentiment measures and refining the selection timing. The article is a brief strategy outline rather than a tested trading system; the meaning and measurement of “main-player control” are not explained.

Key ideas

• The screen combines a minimum amplitude, prior-day main-player control, and prior-day turnover threshold.
• It targets volatile stocks and market themes, but provides no performance evidence.
• The sample implementation adds filters beyond the stated selection rules.
• The author identifies sentiment sensitivity and the omission of fundamentals as limitations.
• Additional technical, fundamental, and sentiment measures are proposed as possible refinements.
