Stock Screening by Turnover, Beverage and Alcohol Industry, and Opening Gap

Summary

The post proposes a stock screen combining turnover between 3% and 12%, membership in the beverage and alcohol industry, and an opening price rise below 6% relative to the previous close. It presents the filters as a short-term speculative selection approach, reasoning that the turnover band reflects trading activity and the opening move constraint may avoid stocks that have risen too sharply before regular trading.

The article includes example screening expressions and a Python outline that filters industry and intraday data. However, its descriptions are not fully aligned: the rule refers to the first 25 minutes before the open, while the code filters five-minute data earlier than 09:30, and also applies a volume-ratio condition. No backtest results or evidence of profitability are supplied. The author notes that the screen may miss stocks rising for other reasons and that a short-term price change does not establish a longer-term trend; additional fundamental and technical filters and testing are suggested.

Key ideas

• The proposed screen combines turnover from 3% to 12%, beverage and alcohol industry membership, and an opening rise below 6%.
• The post frames the filters as a short-term speculative stock selection method.
• The code outline adds a volume-ratio filter and does not exactly match the stated timing rule.
• No performance evidence is provided, and the post identifies missed opportunities and limited trend information as risks.
