Magnificent Seven Correlation Hits Decade Low as AI Splits the Group

The tight synchronization that has defined the performance of the largest technology companies for years has broken down. Data compiled by CNBC shows that the rolling 60-day correlation of daily returns among the seven major tech firms has dropped to its lowest level in more than a decade. This statistical shift indicates that the stocks are no longer moving in unison, compelling investors to evaluate each company on its own merits rather than treating the group as a single trade.

The divergence is visible in the market performance of the group members in 2026. The Roundhill Magnificent Seven ETF, which tracks these companies, has returned 7% year to date. This lags behind the 12% gain achieved by the S&P 500. Within the group, only Nvidia and Apple have outperformed the broader market index. Tesla and Meta are the two members currently posting negative returns for the year, marking a sharp departure from the recent history where the group tended to lead the broader market.

Analysts attribute the split to differing exposures to artificial intelligence. Gil Luria, an analyst at D.A. Davidson, stated that the companies have different AI profiles. He argued that this requires a granular approach to ownership, moving away from holding the stocks wholesale. Thomas DiFazio, an ETF strategist at Roundhill Investments, noted that investors are now focusing on micro factors and independent fundamental growth drivers for each firm.

These drivers vary widely across the seven companies. For Microsoft, the focus is on Azure cloud growth. Meta is being judged on its consumer AI applications, while Apple is evaluated on its device and services ecosystem. Alphabet is scrutinized for its progress in Google Cloud, Gemini, and Search. Amazon's cloud growth and Nvidia's chip demand durability are key metrics for those two firms. Tesla's narrative centers on AI, robotics, and robotaxis, with potential interest in a merger with SpaceX.

Despite the price divergence, Wall Street remains largely bullish on the group's fundamentals. According to LSEG data, 97% of analysts hold buy or strong buy ratings for Amazon and Microsoft. Nvidia also holds a 97% buy rating, while Alphabet sits at 92%. Meta has an 89% buy rating. Apple holds a 58% buy rating, and Tesla is the outlier with 50% of analysts recommending a buy.

Apple has emerged as a standout performer in this new environment. The company has gained 28% in 2026, leading the group. This stands in contrast to 2025, when Apple returned 8.9%, the second worst result in the group behind Amazon's 5.2%. Jay Woods, chief market strategist at Freedom Capital Markets, described Apple as the consistent tortoise in the race. Luria called it the place to hide from the AI trade, noting that views on its AI exposure have shifted positively.

Other members face specific headwinds. Nvidia shares peaked on Oct. 6 and have fallen more than 13% since amid worries over chip demand. Woods described the valuation as relatively and historically cheap. Amazon's cloud unit grew 37% year over year in the second quarter, trailing Azure's 43% growth and Google Cloud's 82%. Meta rose in September on its Muse AI assistant but turned lower after reporting negative free cash flow and a higher floor for full-year capital spending.

Microsoft has recovered from fears that AI would disrupt its software business but now faces resistance in the $530 to $550 range. Tesla has lagged the group, with Luria noting its valuation carries an Elon premium. Earnings reports for Microsoft and Alphabet are scheduled for after the bell on Wednesday, followed by Amazon after the close on Thursday.
