Key takeaways

  • Apple, Microsoft and Tesla drove the S&P 500's decline, with Apple alone digging the biggest hole.
  • More U.S. stocks rose than fell, so the index and the market told different stories.
  • Chipmakers led the Nasdaq-100 higher, with Micron adding more than the fund's whole gain.
  • Small caps rose without any handful of names doing the work.

Apple subtracted 0.18 percentage points from the S&P 500 fund SPY at Friday's close, the largest hole in a 0.39% decline. Microsoft subtracted 0.12 percentage points and Tesla 0.09. Counted name by name, more U.S. stocks still finished higher than lower.

The S&P 500 versus 5,811 U.S. stocks

Of 5,811 U.S. common stocks listed on the NYSE, Nasdaq and NYSE American, 2,946 rose, 2,605 fell, and 260 were unchanged. That is 50.7% advancers, a slight majority. The count excludes ETFs, funds, foreign listings, and currency and crypto symbols.

The two S&P 500 constructions moved together. The Nasdaq-100 and small caps went the other way.

Total return (%), Friday, September 4, 2026

  • Small caps0.26
  • Nasdaq-1000.18
  • S&P 500−0.39
  • Equal weight−0.48

Equal-weight lost more than cap-weight.

Sixteen of the 20 mega-caps in the board fell, including Apple, Microsoft, Amazon, Alphabet, Tesla, Berkshire Hathaway, JPMorgan, and Walmart.

Apple fell 2.5%, Microsoft 2.0%, and Tesla 5.9%. Tesla's drop came after its Cybercab event, with a federal safety review of the vehicle reported the same session. Nvidia, the S&P 500's largest holding at 8.3% of SPY, rose 0.84% and added 0.07 percentage points, not enough to offset Apple.

Micron added more than the Nasdaq-100 gained

Micron, the memory-chip maker, rose 6.1% and added 0.29 percentage points to the Nasdaq-100 fund QQQ, more than the fund's entire 0.18% gain, and only 0.10 percentage points to SPY, where it weighs less. AMD rose 4.7%, Intel 4.5%, and SanDisk, the flash-memory company, 11.9%.

The small-cap fund IWM gained 0.26%, and the eight names that moved it most accounted for 0.01 percentage points of that rise. That is what a gain looks like when it is not a handful.

The read breaks if Monday's advancers fall to 45% or less of the 5,811-name universe, against Friday's 50.7%, while the S&P 500 falls again. Then the index and the market would be telling the same story.
