Stock Screening by Turnover, Opening Price, and Listing Age

Summary

This stock screen selects shares with turnover between 3% and 12%, an opening price within 5% of the 10-day moving average of closing prices, and at least 50 days since listing. The document presents the rules as a way to combine trading activity, proximity to a short moving average, and a minimum listing history. It includes formula and Python examples for applying the filters, as well as a market-type exclusion in those examples.

The text provides the screening conditions but no backtest, portfolio returns, benchmark comparison, or evidence that the filters predict future performance. It also notes that a screen based mainly on technical measures and listing age omits company fundamentals, and suggests considering valuation, earnings expectations, industry context, and market trends. The criteria are therefore a candidate selection rule, not a complete investment process; implementation details, data quality, and out-of-sample results would need separate review.

Key ideas

• The screen requires turnover between 3% and 12% and an opening price within 5% of the 10-day moving average.
• It excludes stocks listed for fewer than 50 days.
• The examples also exclude a market type, although the prose does not explain that filter in detail.
• The document warns that technical filters and listing age leave out company fundamentals and broader context.
• No backtest or performance evidence is provided.
