Chinese Stock Screen Using Volatility, Price, and Institutional Buying

Summary

This Chinese equity screening note proposes combining daily price range, a low share price, and reported institutional buying to find potential candidates. Its stated screen looks for amplitude above 1, a close below 20, and institutional accumulation. It also suggests considering both technical and fundamental information and applying risk controls when selecting stocks.

The document gives example indicator formulas and Python logic, but the implementations do not consistently match the stated rules. The formula’s amplitude condition is not clearly represented, and its institutional volume test compares current buying with rolling totals in a way that may not express the intended signal. The Python example also ranks and truncates stocks before applying filters. No backtest results or evidence of predictive performance are provided. The note itself warns that institutional buying is only one signal and may be misread; the screen should therefore be treated as an unvalidated idea rather than a demonstrated strategy.

Key ideas

• The proposed screen combines price amplitude, a closing price below 20, and institutional buying.
• Institutional purchases are treated as a possible sign of investor expectations, not a guarantee of future gains.
• The examples provide formulas and Python logic, but parts do not clearly implement the stated selection criteria.
• The note recommends adding fundamental and technical analysis and using risk controls.
