Use this when you want to see which stocks actually trade together. Bubbles below are clusters validated by 252-day co-movement; themes are editorial groupings to contrast against; the matrix at the bottom is the raw pairwise view. For the flat sector list instead, that's on /sectors.
Stock groups validated by their actual co-movement over 252 trading days. 12 groups, scored for thematic purity.
Narrative groupings (Space, Photonics, Drones, Nuclear…) curated for screening — 18 themes, with key Fib levels.
Every primary-bubble member crossed against every other — the ground truth the bubbles are inferred from.
252d corris the average pairwise Pearson correlation of the group's primary members over the last 252 trading days. Values above 0.6 indicate real thematic co-movement; values below 0.4 suggest the group is driven more by broad market beta than by idiosyncratic flow.
Stocks that actually trade together. Each bubble is a group whose members co-moved over the past 252 days.
GPUs, accelerators, and the AI-specific silicon stack that moves as one under capital flows.
Picks and shovels of chip manufacturing — the machines that make the machines.
DRAM, HBM, memory IP, advanced packaging, and storage — the memory bottleneck of AI compute scaling. The Samsung+SK Hynix+Micron trio is forecast to print ~$454B in FY26 operating income (Samsung +413% / SK Hynix +593% / Micron +684%) on HBM allocation tightness through 2026.
The subset of mega-caps whose AI capex narrative dominates price action.
Workflow and data-platform SaaS monetizing AI — the legacy-software AI trade.
Moving bits between tens of thousands of GPUs — optical is non-negotiable.
AI eats electricity. Utilities and independent power are the unlock.
Clean baseload for hyperscaler campuses — SMRs and uranium miners.
Physical plant of AI — cooling, switchgear, prefab datacenter components.
Physical AI — industrial, surgical, and humanoid robotics.
Edge compute, global data pipes, earth observation — orbital layer of AI.
Post-GPU compute optionality — long-dated but asymmetric.
Narrative groupings — useful when you screen by story (Space, Drones, Photonics…) rather than by flow.
Net ETF creations minus redemptions over the last 7 days, rolled up per bubble. Where capital is actually showing up — green = net inflow, red = net outflow.
Each square shows how closely two stocks moved together over the past year. Brighter = tighter co-movement. The diagonal blocks line up with the bubbles above.
