Screening Stocks for Volatility, Auction Limit-Down, and Trading-List Activity

Summary

This stock screen combines three conditions: amplitude above one, a prior-day 9:15 auction matched price at the limit-down level, and an appearance on the prior day’s trading list. The article interprets the filters as capturing volatility, weak market sentiment at the auction, and active capital flows. It frames the resulting names as candidates for short-term speculation and urges caution.

The post flags the screen’s high risk, noting that it does not adequately account for company fundamentals or long-term prospects and may be vulnerable to market volatility or price manipulation. It recommends adding fundamental measures, market sentiment and flow analysis, manipulation filters, and capital and risk controls. Example indicator and Python logic is included, but there are no backtest results or evidence that these conditions forecast returns; the criteria alone do not establish an actionable or validated strategy.
