Chinese Stock Screening by Volatility, Limit-Ups, and Fund Strength

Summary

The document describes a Chinese equity screen that combines daily price range, a history of limit-up moves, and a ranking by a measure labeled fund strength. Its stated rules look for stocks with an amplitude above 1%, at least two limit-up events during the past 500 trading days, and stronger fund readings. It also suggests adding indicators such as KDJ or WR, market trend, price gains, and turnover to broaden the assessment.

The post includes formula and Python examples, but they do not consistently implement the stated screen. For example, the Python amplitude condition rejects stocks when average range divided by average close is above 1%, while the prose seeks high-amplitude stocks; the code also uses a dated flow-data query and compares an index to a stock code. No performance evidence or validated backtest is provided. The ranking and event rules therefore serve as a rough screening concept, not proof of investment merit. The document itself cautions that screening is preliminary and that fund strength alone does not capture a stock's value, risk, or market sentiment.

Key ideas

• The proposed screen combines price amplitude with at least two limit-up events over a 500-day lookback.
• Stocks are then ranked by a measure the post calls fund strength.
• The post recommends combining flow measures with other technical indicators and market context.
• Its formula and sample code contain inconsistencies, and the document reports no performance validation.
