Closelook Indices · Compare

Compare anything against anything

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.

FAQ · from the current data

Compare — Q&A

What does the compare page do?

It rebases any mix of Closelook indices and their variants (equal-, cap-, momentum- and active-momentum-weight), sub-indices, stocks and benchmark ETFs to 100 at the first bar inside the chosen window, so different levels plot on one comparable percentage scale. Log scale is the default.

Which series can be compared?

Every Closelook index family — Rubin Build-Out 100, HALO 100, Euro-AI 50, Agentic Winners 40, the Agentic Ecosystem Index and T1 — with all their variants and sub-indices, plus any covered stock or ETF through the symbol search.

Is this investment advice?

No. The compare chart is a data surface in an investment research diary: it shows relative performance over the window you pick and recommends nothing.
