Stock Screening with Dividend Yield, Price Amplitude, and a 250-Day Average

Summary

This Chinese stock-selection post describes a screen combining daily price amplitude above 1%, a 2019 dividend yield above 25%, and the previous close above the 250-day moving average. The proposed rationale is to combine a volatility measure, a historical income measure, and a long-term trend filter. The post supplies indicator formulas and sample code, but it does not present backtest results or evidence that the combined conditions improve returns.

The author cautions that the long moving average can produce whipsaw signals and that market risk remains. Suggested refinements include adding flow or volume measures, other technical indicators, and rules that adapt to market conditions. The examples have implementation ambiguities, including how the historical dividend figure is sourced and the exact alignment of the previous close with the moving average. The screen is therefore best understood as a selection concept requiring data checks and independent evaluation, rather than a validated strategy.

Key ideas

• The screen requires daily price amplitude above 1%.\nIt includes a 2019 dividend yield threshold above 25%.\nIt filters for a previous close above the 250-day moving average.\nThe post warns that long moving averages can generate whipsaws and offers no performance evidence.
