Screening Main Board Stocks by Turnover, Daily Gain, and Float Value

Summary

The document presents a Chinese A-share stock screen that selects main board names with turnover between 3% and 12%, a daily gain above 1%, and circulating market capitalization above 10 billion yuan. It provides indicator-formula references and a Python example that checks recent observations for turnover, percentage change, and float value, while also filtering for codes associated with the Shanghai market and excluding ST-designated stocks. The article characterizes the market-capitalization threshold as a way to remove smaller-float stocks.

This is a screening rule rather than a complete portfolio or trading system: it does not specify entry timing beyond the daily conditions, exit rules, weighting, or risk controls. It provides no backtest results or evidence that the screen is profitable. The author notes that the approach relies mainly on technical inputs and omits company fundamentals and industry prospects, suggesting that profitability, valuation, growth, sector information, or additional indicators could be considered. Such additions are suggestions, not tested improvements in the document.

Key ideas

• The screen requires turnover from 3% to 12%, a daily rise above 1%, main board status, and circulating market value above 10 billion yuan.

• The article offers formula references for implementing the screening conditions.
• The screen does not include exit rules, portfolio construction, or reported performance results.
• The author identifies missing fundamental and industry information as a limitation.
