Chinese Stock Screen Using Intraday Range, Main-Force Control, and 龙虎榜 Activity

Summary

This post describes a Chinese equity screening rule that looks for stocks with an amplitude greater than 1, signs of main-force control on the previous day, and a 龙虎榜 appearance on the previous day. It frames range as a measure of activity, main-force control as an indication of capital flow, and the ranking-list appearance as a signal of market attention. A code example adds filters such as positive daily change, trading at the high, and sorting by market capitalization; these implementation details do not exactly reproduce the written rule.

The post warns that 龙虎榜 activity can reflect short-term speculation rather than company prospects, and that the simple screen omits fundamentals and valuation. It also notes that a widely followed rule may contribute to volatility. The article offers no backtest results or evidence that the screen identifies growth stocks reliably. Its suggested improvements include adding fundamental, technical, valuation, and risk-management considerations, so the rule is best understood as an activity-based candidate screen rather than a complete trading strategy.

Key ideas

• The screen combines a high amplitude condition with previous-day main-force control and 龙虎榜 activity.
• The post treats range as a proxy for volatility and the ranking-list signal as a proxy for market attention.
• Its code example includes additional price-action filters that differ from the written screening rule.
• The author cautions that ranking-list activity may reflect short-lived speculation and says fundamentals and valuation are omitted.
• No performance evidence is provided, and the post recommends broader analysis and risk control.
