Screening Main-Board Stocks by Turnover, Daily Gains, and Limit-Ups

Summary

This short-term stock screen selects main-board shares with turnover between 3% and 12%, a daily gain above 1%, and more than two limit-up days within a ten-day window. The article frames turnover and daily gains as signs of activity, while repeated limit-ups are treated as evidence of market attention and speculative demand. It gives example indicator logic and Python-style screening code, but does not report a backtest, returns, or risk-adjusted performance.

The method focuses on recent price action and trading activity, with no fundamental valuation or business-quality test. The article acknowledges that this can overlook a company's underlying condition and expose the selection to market swings. It suggests adding fundamental measures and risk controls. Since the provided code's limit-up calculation may not accurately identify exchange price limits, any implementation would need to define limit-up events correctly for the relevant security and date before evaluating the screen.

Key ideas

• The screen requires turnover between 3% and 12%, a daily gain above 1%, and more than two limit-up sessions in ten days.
• It targets main-board stocks and uses recent trading activity as a proxy for market interest.
• The article provides no backtest results or evidence of strategy performance.
• The screen omits company fundamentals and may be exposed to sharp price swings.
• Limit-up event logic should be validated before implementing or testing the screen.
