Closelooknet rankings · Up & Down Beta
Stocks that fall more with the market than they rise
The stocks with the most negative gap between up-day beta and down-day beta — names that suffer in sell-offs more than they participate in rallies, over the last 126 trading days.
The mirror list: stocks whose down-day beta is larger than their up-day beta, with downside participation in the top of their own one-year range. In plain words — when the market drops, these names drop harder; when it rallies, they lag. Strong stocks appearing here early is often the first structural warning.

Up-beta / down-beta: how much the stock moves on the market’s up days and down days, over the last 126 trading days. Beta gap = up-beta minus down-beta. Instability = how far the current beta has drifted from its own history (0–100).

FAQ
What are up-beta and down-beta?
Beta measures how much a stock moves when the market moves. We split it in two: up-beta is measured only on the market’s up days, down-beta only on its down days. A stock with up-beta 1.4 and down-beta 0.8 rises more with rallies than it falls in sell-offs — the two numbers rarely match, and the gap between them is the interesting part.
What does the state column mean?
Our engine sorts every stock into one of five states: healthy leader (strong upside participation, positive beta gap), neutral, fragile (negative gap with elevated downside beta), distribution (fading upside with beta-adjusted underperformance) and decoupling (the relationship with the market itself is breaking down).
How often is this ranking updated?
The engine runs after every US market close across our full coverage, measured against the S&P 500. This page is rebuilt every morning and always shows the date of the run it was built from.
