Combining Volatility, Institutional Flow, and a Morning Star Stock Signal

Summary

This Chinese-language post describes a daily, after-close stock screen combining three conditions: a five-period amplitude measure above a threshold, a change in institutional participation rate, and a named morning-star indicator associated with a particular stock. It presents the combination as a way to select equities with elevated price movement, a shift in institutional activity, and a technical reversal signal. The post also supplies indicator expressions and illustrative implementation code, though the formulas and data fields are platform-specific and should not be assumed to work as written elsewhere.

The post warns that relying heavily on historical technical data can limit signal sensitivity and validity, and that a short-term screen cannot account for all market uncertainty. It suggests adding measures such as returns, turnover, valuation, live fund flows, and sector direction. No backtest results, sample definition, transaction costs, or evidence of predictive accuracy are provided, so the proposed logic is best treated as a screening hypothesis requiring independent validation and risk controls.

Key ideas

• The screen selects stocks after the close using a price-amplitude condition, institutional participation change, and a morning-star indicator.
• The three filters combine price activity, a measure of institutional flow, and technical analysis.
• The author flags dependence on historical technical data and short-term focus as sources of uncertainty.
• Additional return, turnover, valuation, flow, and sector measures are proposed as possible refinements.
• The post provides no performance study, and its platform-specific indicators require validation before practical use.
