Closelook rankings · Up & Down Beta

Stocks whose market relationship is breaking loose

The stocks whose beta to the market has moved furthest and fastest away from its own history — the least stable market relationships in our coverage right now.

This list ranks by beta instability: how far a stock’s current beta has moved away from its own history, and how fast. A high number does not say up or down — it says the old relationship with the market is not holding, which is when position sizing built on that old relationship stops being reliable.

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.
