Chinese Stock Screen for High Volatility, Auction Value, and Institutional Buying

Summary

This Chinese-language post outlines an equity screening idea that combines stocks with amplitude above a stated threshold, the five highest opening-auction amounts for the day, and a proxy for institutional buying. It gives a corresponding indicator-formula reference and a Python example intended to return a limited list of candidates. The proposed rationale is that large price movement and strong auction activity may identify active stocks, while institutional buying may signal interest.

The post cautions that the screen can miss company financial conditions and that institutional activity can be misread, including when policy or other factors affect trades. It suggests adding fundamental measures such as profitability and growth, and examining whether institutions are increasing holdings or selling and why. The examples are references rather than a validated backtest: the document reports no returns, risk statistics, or evidence that the screening signals predict gains.

Key ideas

• The screen combines a price-amplitude filter, opening-auction amount ranking, and a proxy for institutional buying.

• Its stated rationale is that active trading and institutional interest may help identify stocks for review.
• The author notes that company fundamentals and the reasons behind institutional trades are not captured well.
• No backtest results or performance evidence are provided.
