The September 4, 2026 U.S. regular session (09:30~16:00 ET) saw diverging moves between large-cap indexes, which fell, and the small-cap index, which rose. Among tracked stocks, Tesla’s sharp decline and the surges in SanDisk and Micron clearly split the day’s closing performance.

It opened at 7,750.19 points, reached an intraday high of 7,750.19 points and a low of 7,706.12 points, with volume of 2,529,297,000 shares. S&P 500 closing data and Trading Economics’ September 4, 2026 index quote provide sources for that day’s lower close.

This means large-cap and small-cap indexes moved in different directions at the close; the cause cannot be identified from their simultaneous closing moves alone. See Nasdaq Composite, Dow Jones, and Russell 2000 closing data.
Tesla -5.92%, with Apple and Microsoft also down more than 2%
Tesla closed the regular session on September 4, 2026 at $354.08, down $22.29, or 5.92%. It opened at $362.07, reached an intraday high of $364.69 and a low of $351.32, with volume of 64,375,359 shares. This was the largest closing decline among the tracked stocks and a drop 5.63 percentage points greater than the Nasdaq Composite’s 0.29% decline on the same trading day. Tesla closing data and the Tesla stock hub provide further historical analysis.
Apple closed September 4, 2026 at $319.97, down $8.24, or 2.51%, while Microsoft ended at $499.70, down $10.42, or 2.04%. Apple’s intraday low was $317.86 and its volume was 38,007,287 shares. Microsoft’s intraday low was $499.36 and its volume was 17,366,403 shares. See Apple closing data and its stock hub, as well as Microsoft closing data and its stock hub.
Alphabet stood at $338.46 on September 4, 2026, down $4.02, or 1.17%, while Amazon was at $258.51, down $0.39, or 0.15%. In contrast, Nvidia closed at $230.36, up $1.91, or 0.84%, and Meta ended at $616.77, up $6.09, or 1.00%. These figures show that the closing directions of the tracked large technology stocks were not uniform. See Nvidia and its stock hub, along with Meta and its stock hub.
Contrast between SanDisk’s 11.90% gain and Micron’s 6.10% rise
SanDisk closed September 4, 2026 at $1,740.00, up $185.01, or 11.90%. It opened at $1,586.00, with an intraday high equal to its closing price of $1,740.00 and a low of $1,581.00, while volume totaled 15,848,273 shares. SanDisk closing data and the SanDisk stock hub provide that trading day’s figures and prior records.
Micron closed the regular session on the same trading day at $1,016.59, up $58.43, or 6.10%. Its intraday high was $1,017.77, its low was $969.00, and volume was 34,720,174 shares. The gains in both stocks moved in the opposite direction from the S&P 500’s 0.38% decline and the Nasdaq Composite’s 0.29% decline. In editorial interpretation, rather than reading the day’s index weakness as uniform weakness across all individual stocks, it is necessary to consider differences in individual closing performance as well. See Micron closing data and the Micron stock hub.
Higher yields and dollar, and the context cited in reports
The U.S. 10-year Treasury yield closed September 4, 2026 at 4.784%, up 0.022 percentage points. The dollar index rose 0.164 points, or 0.17%, to 99.164. The VIX ended at 14.55 points, up 0.23 points, or 1.61%. WTI crude oil rose $0.04 per barrel, or 0.04%, to $91.34. The same-day figures are available through U.S. 10-year Treasury yield, dollar index, VIX, and WTI crude oil closing data.
Investopedia’s original September 4, 2026 market article cited both falling indexes and rising Treasury yields in its headline. This is the market context presented in the report; the same-day closing changes in those indicators and stock indexes alone cannot establish that yields or the dollar caused the decline in equities. Dollar-won closed September 4, 2026 at 1,344.76 won per dollar, down 10.65 won, or 0.79%. See dollar-won closing data.
Three items to check in the next regular session
-
It can be checked whether the divergence among indexes continues at the next regular-session close after the S&P 500 fell 0.38%, the Nasdaq Composite fell 0.29%, and the Dow Jones fell 0.51%, while the Russell 2000 rose 0.25% on September 4, 2026.
-
Following Tesla’s 5.92% decline, SanDisk’s 11.90% gain, and Micron’s 6.10% rise on September 4, 2026, the closing price movements of those three stocks can be reviewed alongside the directions of Nvidia and Meta.
-
The next regular-session closing figures can be checked for the VIX, which stood at 14.55 points on September 4, 2026; the U.S. 10-year Treasury yield, which was 4.784%; and the dollar index, which was 99.164 points.
