Composite Index — since inception (Mar 31, 2026)

Three weighting variants of the same constituent basket, rebased to 1,000 at inception (2026-03-31 for the v8.5 Euro-AI family). EW = ticker-equal-weight with quarterly drift. CW = cap-weighted (10% cap; below ten names the cap is infeasible, so the sub-index is equal weight by construction) with semi-annual rebalance. MW = drift-only (1/N at inception, market does the tilting between rebalances). Click a legend entry to toggle its line.
