Screening Stocks for Volatility, Recent Limit-Ups, and Market Attention

Summary

This document proposes a stock watchlist screen that selects shares with daily amplitude above a threshold, at least one limit-up event during the prior 25 days, and high ranking by market attention. It frames amplitude as a way to find volatile stocks, a recent limit-up as evidence of market interest, and attention ranking as a short-term popularity measure. It includes example formulas and Python-like code, although those examples do not clearly implement the stated lookback and ranking logic.

The discussion cautions that attention may not reflect company quality, historical screening may not predict future returns, and volatile stocks can carry substantial risk. It suggests adding fundamental, technical, industry, and macroeconomic information and reconsidering ranking weights. The document provides no backtest, return data, or detailed method for measuring attention, so the proposed signal should be treated as an unvalidated selection concept rather than an established strategy.

Key ideas

• The proposed watchlist combines amplitude, a limit-up event within a recent lookback, and an attention ranking.
• The document treats limit-ups and attention as signs of market interest, not proof of business quality.
• It warns that high volatility and historical selection signals may lead to poor outcomes.
• The sample code does not clearly match all parts of the stated screening logic.
• No performance evidence or precise attention measure is provided.
