Rubin Equal Weight
Passive buy-and-hold of the Rubin Build-Out 100 constituents at inception-date equal weights. Notional 500k USD.
Thesis
Rubin Equal Weight is the passive reference expression of the Rubin Build-Out thesis: if you believe the AI capital cycle plays out across all 100+ constituents roughly symmetrically, you buy every name at the same dollar weight and let time compound. No factor tilt, no sector concentration. A pure bet on the breadth of the thesis.
Inception: 2026-01-02 with 500,000 USD notional, spread equal-weight across the Rubin-Index constituents at their local-currency entry prices, FX-converted to USD at the inception-date spot rate. Fractional shares permitted. No rebalancing between inception and today — the portfolio drifts naturally as winners grow their weight and laggards shrink. Divergence from the live CL-RUBIN-EW index (which rebalances daily to maintain equal weights) is an expected feature, not a bug — the buy-and-hold version is what a retail investor can actually replicate.
