Mag Seven ETF Trailing S&P 500 by 5 Points as AI Bets Diverge

Investors holding the "Magnificent Seven" as a single trade are seeing their portfolios lag the broader market in 2026. The Roundhill Magnificent Seven ETF, which tracks the group's seven members, has returned 7% year to date. The S&P 500 has gained 12% over the same period. This five-point gap reflects a breakdown in how these mega-cap stocks move together.

CNBC analysis of rolling 60-day daily returns shows the average correlation among the 21 unique stock pairs in the group has fallen to its lowest level in more than a decade. The cohort comprises Alphabet, Amazon, Apple, Meta Platforms, Microsoft, Nvidia, and Tesla. Historically, these stocks traded as a cohesive block due to their market influence. That dynamic has shifted as investors focus on independent fundamental growth drivers.

Performance within the group has split sharply. Apple and Nvidia are the only two names outperforming the S&P 500 so far this year. Tesla and Meta are the only two members with negative returns for 2026. Apple's 28% gain leads the pack, reversing its position as the second worst performer in 2025 when it returned 8.9%. Nvidia shares have also been volatile, falling over 13% from their October 6 peak amid concerns about chip demand durability.

Analysts attribute the divergence to differing exposures to artificial intelligence. Gil Luria of D.A. Davidson noted that the group requires a granular approach to ownership rather than wholesale purchases. Thomas DiFazio of Roundhill Investments said investors are now focusing on micro factors such as company-specific news. For Microsoft, the market watches Azure cloud growth. For Meta, scrutiny centers on the revenue potential of its new consumer AI assistant, Muse.

Specific business metrics are driving the valuation splits. Amazon Web Services revenue grew 37% year over year in the second quarter, lagging Azure's 43% growth and Google Cloud's 82% increase. Tesla's investment case now rests more on robotics and robotaxis than on electric vehicle sales. Luria questioned Tesla's inclusion in the group, citing an "Elon premium" in its valuation.

Wall Street remains largely bullish on individual stocks despite the dispersion. According to LSEG data, 97% of analysts rate Amazon, Microsoft, and Nvidia as buy or strong buy. Alphabet and Meta follow at 92% and 89% respectively. Apple holds a 58% buy rating, while Tesla sits at 50%. Microsoft and Alphabet report earnings after the bell Wednesday. Amazon posts results after the close Thursday.

Jay Woods of Freedom Capital Markets described the stocks as the best to own but noted they are starting to separate and go in their own directions. He characterized Apple as a consistent performer in the race, while viewing Nvidia's current price level as relatively cheap historically. The upcoming earnings reports will test whether these companies can maintain their momentum or face further technical resistance.
