The figures below are all based on U.S. regular-session closing data for September 11, 2026. Index levels and changes from the previous day are in points, while percentage changes are in %.

Dow Jones 52,573.29 +509.19 (+0.98%)
Russell 2000 2,903.94 +12.99 (+0.45%)

According to S&P 500 closing data, the S&P 500 closed at 7,656.98 points on September 11, 2026. It opened at 7,636.75 points, reached an intraday high of 7,677.02 points and an intraday low of 7,636.75 points, with volume of 2,652,505,000 shares.

Nasdaq Composite closing data show that the Nasdaq Composite rose 251.31 points (0.96%) to 26,333.04 points on September 11, 2026. The Dow Jones closing data show that the Dow Jones gained 509.19 points (0.98%) to 52,573.29 points on the same trading day, while Russell 2000 closing data show that the Russell 2000 rose 12.99 points (0.45%) to 2,903.94 points. On a closing basis, the large-cap indexes posted larger gains than the small-cap index, but this simultaneous movement alone cannot identify the reason.

Amazon, Alphabet, and Apple advance; SanDisk moves in the opposite direction

According to Amazon closing data, Amazon closed at $256.78 on September 11, 2026, up $4.89 (1.94%). Its intraday high was $257.59, its low was $253.14, and volume was 25,899,455 shares. Previous analysis is available through the Amazon stock hub.

Its intraday high was $1,720.33, its low was $1,616.80, and volume was 9,293,574 shares.

Nvidia remains near flat; other large technology stocks rise

According to Nvidia closing data, Nvidia closed at $218.29 on September 11, 2026, down $0.07 (0.03%). Its intraday high was $222.00, its low was $218.15, and volume was 85,571,151 shares. Closing data confirm that Nvidia ended with a slight decline near flat on a day when the Nasdaq Composite rose 0.96%, but this cannot be interpreted as either a cause or result. Previous analysis is available through the Nvidia stock hub.

Microsoft closed at $495.63 on September 11, 2026, up $3.19 (0.65%), while Meta closed at $648.03, up $3.65 (0.57%). Meta’s intraday high was $664.24, and its low was $646.20. Previous analysis is available through the Microsoft hub and Meta hub.

Sharp VIX decline and lower oil prices; reported interpretations are separate

At the close on September 11, 2026, the VIX fell 2.00 points (11.21%) to 15.84 points. WTI crude oil declined $2.26 (2.21%) to $100.22 per barrel, while the U.S. 10-year Treasury yield rose 0.031 percentage points to 4.975%. The U.S. Dollar Index rose 0.035 points (0.04%) to 99.125 points.

These were closing changes observed together on September 11, 2026. In editorial interpretation, stock-index gains, declines in the VIX and WTI crude oil, and a rise in the U.S. 10-year Treasury yield occurred at the same time, but simultaneous closing movements alone cannot establish that any one indicator drove stock-price movements.

The collected Charles Schwab article cited lower oil prices, the August CPI inflation report, and uncertainty surrounding the Federal Reserve’s interest-rate path as market background in its headline and summary. The Investopedia article cited index gains after key inflation data in its headline. These are the interpretations presented by the two reports; regular-session closing data do not independently establish those causal relationships.

Three items to review in the next regular session

  1. Track how the September 11, 2026 closing levels of 7,656.98 points for the S&P 500, 26,333.04 points for the Nasdaq Composite, 52,573.29 points for the Dow Jones, and 2,903.94 points for the Russell 2000 change at the next regular-session close.

  2. Review the differences in stock-specific direction shown on September 11, 2026: Amazon at $256.78 (up 1.94%), Alphabet at $338.50 (up 1.77%), SanDisk at $1,633.35 (down 3.50%), and Nvidia at $218.29 (down 0.03%).

  3. Review together the next regular-session closing changes in the VIX, which stood at 15.84 points on September 11, 2026; WTI crude oil, which stood at $100.22 per barrel; and the U.S. 10-year Treasury yield, which stood at 4.975%.
