Chinese Stock Screening with Amplitude, Turnover, and Institutional Buying

Summary

This Chinese equity screening idea combines three conditions: price amplitude above a stated threshold, turnover between 2% and 9%, and a signal interpreted as institutional buying near a market low. The article presents institutional accumulation as a possible clue about a stock’s position in the market cycle, while amplitude and turnover describe price movement and trading activity. It includes a formula reference and sample Python intended to illustrate parts of the screening process.

The author flags substantial limitations. Institutional bottom-fishing is ambiguous and may be misclassified or simply wrong; the screen also emphasizes trading activity while omitting fundamentals, policy developments, and other market drivers. No measured returns, benchmark comparison, or validation procedure is provided. The code’s data fields and institutional-buying proxy do not clearly establish that it implements the stated signal consistently. The article suggests adding fundamental measures and risk controls such as dynamic exits, but does not define or test those additions.

Key ideas

• The screen combines price amplitude, a turnover band, and a proxy for institutional buying.
• The article treats institutional accumulation as a possible market-bottom clue, not a reliable prediction.
• Its examples include formula and Python references, but the institutional signal is not clearly validated.
• Fundamental factors and explicit risk controls are absent from the core screen.
• No backtest results or evidence of profitability are reported.
