Combining Consecutive Declines, Volatility, and Main-Fund Control in Stock Screening

Summary

This note outlines a Chinese equity screen based on amplitude above 1, a signal described as main-fund control on the previous day, and three consecutive declining sessions. The proposed rationale is that elevated price movement and apparent large-investor involvement may identify stocks that have recently weakened but could rebound. The article frames this as a combination of technical and capital-flow signals, rather than presenting it as a tested trading system.

The stated caveats are material: the screen omits company fundamentals, and the article says backtests found the selected stocks generally carried high risk, without giving figures or methodology. It recommends adding technical indicators, measures of profitability and asset quality, and closer analysis of fund flows and trading activity. The included code is explicitly illustrative and has unclear or inconsistent condition logic, so it should not be treated as a faithful, validated implementation. No performance evidence is supplied to establish that a rebound edge exists.

Key ideas

• The proposed screen combines amplitude above 1, previous-day main-fund control, and three consecutive declining sessions.
• The strategy assumes recent declines alongside fund involvement may precede a rebound.
• The article warns that the screen ignores fundamental company information and may select high-risk stocks.
• It recommends combining technical, fundamental, and capital-flow analysis.
• The sample code is illustrative and does not establish a validated strategy.
