Screening Chinese Stocks by Amplitude, Prior Limit-Up Status, and Float Value

Summary

This post describes a Chinese equity screen that selects stocks with daily amplitude above 1%, excludes stocks that closed at the daily limit-up on the previous session, and requires circulating market capitalization above 10 billion yuan. It defines circulating market value as the value of publicly tradable shares and presents larger float value as a way to focus on larger companies. The post includes indicator formulas and a sample selection workflow using daily price data.

The screen is a basic filter, not a complete investment strategy. The source itself notes that it does not account for broader technical or fundamental conditions and suggests adding indicators such as MACD, RSI, valuation ratios, dividends, and market trend. Its sample code and prose are not fully consistent about the market-cap threshold, and the document supplies no backtest results, execution assumptions, or evidence that the filter predicts returns. The final portfolio construction claim is therefore not demonstrated by the material shown.

Key ideas

• The screen requires amplitude above 1%, a prior session without a limit-up close, and float value above 10 billion yuan.
• Amplitude is calculated from the session high and low relative to the prior close.
• The post presents float market capitalization as a way to focus on larger publicly traded companies.
• The source recommends combining the screen with technical, valuation, dividend, or market-trend measures.
• No performance test or evidence of predictive value is provided.
