Screening Stocks for Volatility, Proximity to the 10-Day Average, and Price Change

Summary

This Chinese-language post outlines an equity screen intended to find possible short-term rebounds among stocks in a pullback. It combines three filters: prior-session amplitude above 1%, an opening price within 5% above or below the 10-day moving average, and a price change between -2% and 5%. The example formulas show how to combine the conditions and rank qualifying names by volume. The post also suggests adding fundamental measures and using multiple technical indicators.

The rationale is that larger amplitude signals greater short-term fluctuation, an open near the moving average may indicate a correction, and a bounded price change may leave room for a rebound. These are hypotheses rather than demonstrated findings: the document provides no backtest or return data. The code examples also differ in how they calculate amplitude and price change, and the stated price-change calculation may not represent an opening auction move. The screen omits fundamentals by design and requires separate risk controls.

Key ideas

• The screen combines amplitude above 1%, an open within 5% of the 10-day average, and price change between -2% and 5%.
• The stated aim is to identify stocks in a pullback that may rebound over a short horizon.
• The example ranks qualifying stocks by volume after applying the filters.
• The post warns that the screen omits fundamental information and that volatile candidates can carry greater risk.
• No performance evidence is given, and the code examples use differing calculations for some inputs.
