S&P 500 down 0.19% while equal‑weight index rises; Magnificent Seven now under 30% of value, sparking a shift to non‑tech stocks.

The S&P 500 closed 0.19% lower yesterday, but the equal‑weight version of the index edged up, highlighting a widening gap between the “Magnificent Seven” tech giants and the rest of the market [1].

| At a glance | |
|---|---|
| S&P 500 price change | –0.19% |
| Equal‑weight S&P 500 change | +0.01% (marginally up) |
| Magnificent 7 share of S&P | < 30% (down from > 30%) |
| Year‑to‑date S&P gain | +1.73% |

## Rotation away from the tech giants

The seven AI‑heavy stocks—Alphabet, Amazon, Apple, Meta, Microsoft, Nvidia and Tesla—have slipped from a dominant > 30% weighting in the index to just under that level, according to Fortune’s market recap [1]. Only Alphabet and Amazon remain in positive territory; Meta is down 4.39% and Apple down 3.98% year‑to‑date. Analysts attribute the shift to slower earnings growth for the tech cohort and a reallocation of cash from buybacks to AI‑related capital spending [1].

Morgan Stanley’s Lisa Shalett notes that earnings acceleration is now favoring the “493” non‑tech constituents, while tech buy‑back activity wanes [1]. Yardeni Research observes that the broader “Impressive‑493” has outperformed the Magnificent 7 since November and is expected to keep leading in 2026 [1].

## A narrow rally powered by a few tech stocks

Across the broader market, the S&P 500 extended its nine‑week winning streak with a modest 0.2% gain on Friday, lifting the index 19.5% since the March 30 low [2]. Yet that rally is heavily concentrated: technology now accounts for about 35% of the index, versus roughly 20% a decade ago [2]. Many sectors—industrial, consumer discretionary and others—have lagged the rally, underscoring the risk of a market driven by a limited set of AI and semiconductor names [2].

The divergence between the cap‑weighted and equal‑weight indices suggests that while the overall market is still rising, the bulk of that gain is coming from the smaller, non‑tech segment of the S&P 500 [1].

## What to watch
- Upcoming earnings reports from the remaining Magnificent 7 members, especially Apple and Meta, for clues on whether the de‑concentration trend will accelerate.  
- The next Federal Reserve policy meeting (scheduled for July 31) for potential shifts in risk appetite that could affect tech‑heavy versus broader market dynamics.  
- The performance of the S&P 400 and S&P 600 indices, which have been outpacing the S&P 500 and may signal further breadth in the rally [1].

The market’s current split—cap‑weighted indices still buoyed by a handful of AI leaders while equal‑weight stocks hold steady—raises the question of how long the tech‑driven rally can sustain itself without broader sector participation.
