Screening Stocks by Turnover, Seven Down Sessions, and Control Ratio
Summary
This stock-selection rule seeks names with turnover between 3% and 12%, seven consecutive declining sessions, and a current control ratio above 21%. The article frames the conditions as a way to combine trading activity, a short-term falling price pattern, and a measure intended to reflect investor control or interest. It includes a formula-style expression and a Python example, but supplies no backtest, performance figures, or evidence that the control ratio predicts a rebound.
The stated limitations are that the screen relies on short-term technical inputs, may miss fundamentals and longer-term trends, and depends on a control-ratio measure with possible inaccuracies. The article suggests adding volume, valuation, profitability, or other factors and adjusting the rule to market conditions. The formula and code should be checked carefully: the formula includes a volume-growth condition that is not part of the plain-language rule, while the Python example expresses the declining-price condition differently. Data field definitions and the intended meaning of seven down sessions therefore need verification before use.
Key ideas
- The stated screen combines turnover from 3% to 12%, seven declining sessions, and control ratio above 21%.
- The rule is presented as a short-term technical screen rather than a complete valuation method.
- The document offers code-like examples but provides no performance test or evidence of predictive value.
- The formula and Python example contain conditions that do not align fully with the plain-language description.
- The article recommends adding other market or fundamental measures and accounting for data limitations.
