British American Tobacco, Colgate-Palmolive, Realty Income, FICO, Waste Connections, Ford, and McKesson do not exactly share a business plan. Lately, they have shared a trading rhythm anyway.
Jodie’s screen finds 40 stocks whose recent residual co-movement is unusually strong. On August 3, 38 of the 40 were above the activity threshold. The striking part is not simply that many stocks were above the activity threshold that day. The broad market’s up and down moves were stripped out first. This is the part left over: these names moved together beyond the market’s general direction.
Their recent average pairwise correlation was 0.68. Their longer-run baseline is 0.04. In plain English, they normally barely track one another. Recently, the group has behaved much more like a shared trade. That jump is 3.4 standard deviations above normal, a large departure from its own history.
The obvious link is that there is no obvious link. Consumer Defensive is the largest sector, with nine names and 22.5% of the group. But the full universe spans eight sectors, including real estate, financial services, technology, industrials, consumer cyclical, communication services, and healthcare. That is not a tidy industry basket waiting to be explained by one familiar label.
The recent moves make the contrast sharper. Kimberly-Clark fell 3.5% over the last six sessions, while British American Tobacco declined 2.1%, Colgate-Palmolive dropped 2.3%, and Kenvue slipped 2.4%. Stride was down 11.3%. Mondelez, meanwhile, rose 1.8%. Performance Food Group was nearly flat, down 0.1%.
Those figures are not evidence that one stock pushed another around. They are simply examples of a diverse set of companies showing unusually related residual moves over the same recent window. The group’s 589 significant pairwise links underline how broad the pattern is, but they do not supply a cause.
That distinction matters. A high correlation can describe a market pattern without explaining it. It does not say which stock moved first, whether one company influenced another, or whether the shared behavior belongs to fundamentals, positioning, macro exposure, or something else. The data here establish the resemblance, not the reason.
What makes this episode unusual is therefore the combination: 38 active names, eight sectors, and a correlation reading of 0.68 against a baseline of 0.04. Consumer staples are the biggest slice, but they are not the whole meal. The screen has found a cross-sector cluster that recently looked far more unified than its membership would suggest.
This is a descriptive co-movement observation from jodie’s analytics, not investment advice.
