A Rising-Base Stock Screen with Amplitude and Turnover Filters

Summary

This screening concept selects stocks with price amplitude above 1, rising lows or a higher base, and turnover between 2% and 9%. The post presents the criteria as a way to combine price structure with trading activity and liquidity. It also suggests broadening the screen with relative-strength or unusual-activity measures and fundamental indicators such as valuation and revenue growth. Formula and Python sketches are included, but there is no specified portfolio, trading plan, backtest, or reported result.

The author cautions that technical and turnover filters alone may select companies with weak long-term prospects, and that fixed turnover bounds may not suit every stock or market regime. The code examples should be interpreted carefully: one Python condition uses volume changes as a substitute for turnover, while the formula's definition of a rising base is not fully explained. These gaps make the post an outline for a screening idea rather than a validated strategy.

Key ideas

• The screen combines amplitude above 1, a rising price base, and turnover between 2% and 9%.
• Turnover is intended to help account for trading activity and liquidity.
• The author notes that the screen omits company fundamentals and uses fixed thresholds.
• Possible additions include relative strength, unusual activity, and fundamental measures.
• The implementation sketches have ambiguities and provide no performance evidence.
