A-Share Screening with RSI, Beverage Industry, and Bollinger Bands

Summary

This document describes a stock screen for the Chinese beverage and alcohol import-export industry. It selects shares with a 14-period RSI below 65 and a closing price above the Bollinger middle band but below the upper band, using a 20-period moving average and two standard deviations. The accompanying Python example also filters for market capitalization of at least 200 million and excludes ST stocks, although those extra filters are not part of the stated final logic.

The article explains the indicators as ways to assess recent price strength and price position relative to historical volatility. It offers no backtest, performance figures, or evidence that the combined conditions predict returns. It cautions that prices can move beyond Bollinger Bands and that the bands alone omit other influences. It suggests adding indicators or company growth measures and tuning parameters, but provides no tested optimization procedure. Treat this as a screening recipe, not a validated strategy.

Key ideas

• The screen requires a 14-period RSI below 65 in the specified beverage and alcohol import-export industry.
• It selects closing prices between the 20-period Bollinger middle and upper bands.
• The Python example adds market-capitalization and ST-status filters beyond the stated final logic.
• The article provides no backtest results and warns that volatility can make band-based signals misleading.
• Additional indicators, company fundamentals, and parameter tuning are suggested but not evaluated.
