Dividend and Bollinger Band Filters for Chinese Stock Selection

Summary

This stock screen combines daily price movement, a historical dividend-yield threshold, and a Bollinger Band position. It selects shares whose intraday range exceeds 1% of the open, whose stated 2019 dividend yield is above 25%, and whose close lies above the 20-period moving average but below the upper band, defined as the average plus two standard deviations. The lower band is calculated but not used in the final filter.

The accompanying rationale is to seek stocks with recent activity and substantial dividends while avoiding closes above the upper band. The post supplies example screening logic in two environments, but reports no backtest, portfolio results, or validation. It cautions that broad market and sector conditions are omitted, the indicator is imperfect, and historical financial data can become stale; it suggests adding market, sector, and updated company metrics.

Key ideas

• The screen requires an intraday high-low range greater than 1% of the opening price.
• It filters for a 2019 dividend yield above 25% and a close between the middle and upper Bollinger Bands.
• The bands use a 20-period average and two standard deviations.
• The source provides example implementation logic but no performance testing.
• Market, sector, and financial-data timing risks may affect the selection.
