All figures below are based on September 10, 2026 U.S. regular-session closing data. Index levels and changes from the prior day are in points, and percentage changes are in %.

Major Index September 10, 2026 Close (Points) Change From Prior Day (Points, %)
S&P 500 7,591.70 -44.66 (-0.58%)
Nasdaq Composite 26,081.72 -171.62 (-0.65%)
Dow Jones 52,064.10 -316.56 (-0.60%)
Russell 2000 2,890.95 -30.29 (-1.04%)

Based on S&P 500 closing data, the S&P 500 closed at 7,591.70 points on September 10, 2026, down 44.66 points (0.58%). It opened at 7,594.74 points, reached an intraday high of 7,612.86 points and a low of 7,580.06 points, with volume of 2,742,729,000 shares.

According to Nasdaq Composite closing data, the Nasdaq Composite fell 171.62 points (0.65%) to 26,081.72 points on the same trading day. The Dow Jones, according to Dow Jones closing data, fell 316.56 points (0.60%) to 52,064.10 points, while the Russell 2000, according to Russell 2000 closing data, fell 30.29 points (1.04%) to 2,890.95 points. The simultaneous declines across the four indexes and the relatively larger drop in small caps are evident in the closing data, but those moves alone cannot identify the cause of the declines.

Apple +3.56% and Alphabet +0.59% Closed Differently From the Indexes

According to Apple closing data, Apple closed at $326.57 on September 10, 2026, up $11.23 (3.56%). Its intraday high was $326.68, its low was $316.57, and volume was 69,357,158 shares.

Microsoft also closed at $492.44, up $0.79 (0.16%). The closing gains in Alphabet and Microsoft do not indicate the cause or result of the broader market decline; they show that individual closing directions differed. Related records are available through the Alphabet hub and Microsoft hub.

Based on Micron closing data, Micron closed at $977.41 on September 10, 2026, down $50.36 (4.90%). Its intraday high was $999.00, its low was $973.50, and volume was 25,282,097 shares.

Oil, Yields, and Volatility All Rose; Article Interpretations Are Separate

As of the September 10, 2026 close, WTI crude oil was $102.87 per barrel, up $6.82 (7.10%). The U.S. 10-year yield rose 0.107 percentage points to 4.944%, while the VIX rose 1.50 points (9.11%) to 17.96 points. The U.S. Dollar Index rose 0.315 points (0.32%) to 99.085 points.

These were closing changes observed together on September 10, 2026. From an editorial interpretation, it is clear that the major stock indexes fell on a day when crude oil, the 10-year yield, and the VIX rose, but simultaneous closing moves alone cannot establish that any one indicator caused the stock-market decline.

The collected Charles Schwab original article cited three-digit oil prices in its headline as a factor weighing on the market and said market breadth had narrowed. The Investopedia original article cited PPI inflation in its headline as a backdrop to the index declines. These are interpretations presented by the respective reports and should be considered separately from September 10, 2026 closing data for WTI, yields, and stock indexes.
