Stock Screening with Daily Range, Prior Limit-Up, and Rising Lows

Summary

This stock-selection idea combines three daily price filters: a range threshold, exclusion of stocks that hit the upper price limit on the previous day, and a current low above the preceding low. The stated rationale is to seek active shares with rising short-term price structure while avoiding a subset of sharp prior-day advances. A code example illustrates fetching daily market data and applying related conditions, though the prose description and implementation details do not align perfectly in every respect.

The article provides a screening heuristic, not evidence of predictive performance: it gives no backtest, benchmark, or return and risk statistics. It cautions that rising lows are a simple trend proxy that may weaken or reverse, and that the screen ignores company fundamentals, industry conditions, and broader market context. It recommends combining price screening with those factors and diversification, but does not specify how to do so or define a complete portfolio strategy.

Key ideas

• The screen selects stocks using daily range, a prior-day price-limit exclusion, and rising lows.
• The proposed rationale is to find active shares whose short-term lows are moving upward.
• Rising lows alone can flatten or reverse and do not establish a durable trend.
• The method omits fundamental, industry, and market context and includes no performance evidence.
• The article suggests adding broader analysis and diversification without specifying implementation rules.
