Screening Long-Listed Stocks by Amplitude and Institutional Participation
Summary
This document describes a daily, after-close stock screen combining three conditions: amplitude above 1, institutional participation above 30, and more than ten years since listing. It presents the approach as a way to find established companies that show price movement and institutional interest, and suggests adding market capitalization and performance measures to refine the selection.
The article provides indicator expressions and a Python example, but no backtest, performance evidence, or precise explanation of how the institutional participation measure identifies buying. It cautions that listing age alone cannot prevent financial distress or unstable results, and that stock fundamentals and investor risk preferences still require review. The listed conditions are therefore screening criteria, not evidence of future returns or a complete investment strategy.
Key ideas
- The screen selects stocks with amplitude above 1, institutional participation above 30, and listing age over ten years.
- It is run after the market closes each day.
- The article suggests adding market capitalization and company performance criteria.
- Listing age does not remove the risk of poor fundamentals or financial distress.
