Closelook Indices · Compare

Overlay Closelook indices, stocks, and ETFs on one chart. Every line is rebased to 100 at the start of the common window — the latest inception among the selected series — so index levels, share prices, and currencies become one comparable percent scale.

Quick add

Closelook index families: Rubin Build-Out (CL-RUBIN-*, sector codes), Agentic Ecosystem (CL-AEI-*, tier codes), HALO Growth (CL-HALO-*), Euro-AI (CL-EUROAI-* / legacy EURAI-*), AW40 (CL-AW40-*). Stocks and ETFs load native-currency history; foreign listings come from the Closelook data lake.

The Closelook index family, side by side

The five families measure one thesis from different angles. Rubin Build-Out 100 tracks the AI data-centre supply side — silicon, memory, equipment, foundry, power — where capex lands. Agentic Ecosystem and Agentic Winners 40 sit on the deployment side: the software rails, model layers and business adopters that turn the build-out into operating spend. HALO Growth 100 is the AI-neutral growth control group, and Euro-AI 50 the European sovereign-AI cut. Overlaying them here — rebased to 100 in a common window — shows which side of the barbell the market is paying for right now.
