Stock Screening with Price Amplitude, Dividend Yield, and Float Market Capitalization

Summary

This Chinese equity screen combines three conditions: daily price amplitude above 1%, a stated 2019 dividend ratio above 25%, and circulating market capitalization above 10 billion yuan. The post explains amplitude as a measure of price fluctuation, dividend yield as a signal related to company profitability, and market capitalization as an indicator of company size. It includes sample formula and Python snippets for applying the filters.

The article provides no backtest, selected-stock results, or evidence that the screen reduces risk or improves returns. It acknowledges potential sample-selection bias and notes that too few or too many factors can affect reliability. The code is explicitly presented as an example requiring adjustment, and the descriptions of dividend and capitalization fields may not establish that the implementation matches the stated criteria. Suggested additions such as valuation ratios are not evaluated. The screen is best read as a simple factor-filter example, not a validated investment strategy.

Key ideas
