Forty stocks that normally barely acknowledge each other are behaving like they share a script.
Here's the hard part in plain English: this is residual co‑movement. The broad market's up and down days have been stripped out first, so the pattern you see is these names moving together beyond just "the whole market moved." The recent average pairwise correlation across the group is 0.76. Their longer‑run baseline is 0.04. That gap is 3.5 standard deviations above normal — statistically extreme.
The group is 40 names strong, and it’s not a tidy sector story. Technology is the largest slice at +25% of the group, but this lineup spans eight sectors: healthcare, real estate, consumer cyclicals, communication services, financial services, industrials and consumer defensive are all present. Jodie's novelty score for this particular grouping is 0.94 on a 0–1 scale — meaning this specific mix showing this degree of coherence is rare. Internally, 645 pairwise links passed the significance test, so the clustering isn’t driven by a handful of pairs; it’s broad.
Callouts: some of the bigger recent moves among the flagged names.
- ADP (Automatic Data Processing): +8.6% over the last 6 sessions, last close $263.81. - APPF (AppFolio): +7.2% over 6 sessions, last close $176.06. - BLKB (Blackbaud): +28.1% over 6 sessions, last close $40.06. - CTSH (Cognizant): +25.3% over 6 sessions, last close $53.86. - EXLS (ExlService): +27.7% over 6 sessions, last close $34.35. - G (Genpact): +16.3% over 6 sessions, last close $35.35. - INTU (Intuit): +12.1% over 6 sessions, last close $315.56. - DOX (Amdocs): +8.6% over 6 sessions, last close $55.24.
Those are examples, not a who’s‑who directory. The rest of the group includes six REITs and names from healthcare, consumer defensive and financial services — a heterogeneous set. That heterogeneity is notable: normally unrelated businesses are currently sharing unusually similar residual moves.
You can point at an obvious thread — roughly a quarter of the group is tech, and many of the companies are B2B software or services — but the cluster also includes REITs and snack makers. Jodie's analytics flag the pattern; they don't explain the cause. This is contemporaneous co‑movement only. No single stock is claimed to lead or drag the rest.
So what's the takeaway? Statistically, this is notable: high correlation vs a near‑zero baseline, a 3.5σ gap and a novelty score near one. Practically, it’s a snapshot — a textured, cross‑sector grouping that the models say is unusually synchronized right now.
This is a descriptive co‑movement observation from jodie's analytics, not investment advice.
