Stock Screening by Price Movement, Listing Age, and Heat Ranking

Summary

This selection method screens for stocks with amplitude above 1 and more than one year since listing, then ranks qualifying names by individual-stock heat and takes the top n. The accompanying rationale is that larger price movement may indicate market activity, a longer listing history may provide more stability, and high attention may help identify current market themes. The text suggests refreshing the ranking and potentially combining it with fundamentals, capital flows, or technical indicators.

The document provides a simple amplitude formula and sample Python code, but no backtest or evidence that heat ranking predicts future returns. It also notes that ranking is time-sensitive and that the screen may overlook fundamentally strong large-cap stocks. The code’s purported heat measure is derived from listing dates, so it appears to rank listing age rather than market attention as the prose describes. The selection logic therefore needs clarification before the sample implementation can be treated as a faithful version of the stated strategy.

Key ideas

• The stated screen requires amplitude above 1 and a listing history longer than one year.
• Qualifying stocks are ranked by heat, with the top n selected.
• The document describes heat as a changing measure of market attention.
• The sample code derives its ranking field from listing dates, which does not match that description.
• No backtest evidence is provided, and the ranking may become stale as market conditions change.
