An exchange-traded fund holding the S&P 500 minus those seven names is outperforming the Magnificent Seven group by nearly 17 percentage points this year.

In H1 2026, part of my 2026 framework was confirmed: AI‑driven productivity, industrial strength, and utilities' power‑demand tailwinds played out, while the Iran shock created the only major deviation from expectations.

XMAG has overtaken both RSP and the Mag-7 since May 2026, reversing the first four months of the year when the equal-weight index was leading the breadth rotation trade.
