All four major indexes fell during the U.S. regular session on August 6, 2026, but their losses diverged sharply between the Dow Jones and the Nasdaq Composite. The Dow Jones fell 0.85%, while the Nasdaq Composite slipped just 0.06%. Among the tracked stocks, Microsoft rose 2.54%, while SanDisk plunged 6.81%. The U.S. 10-year Treasury yield and the U.S. Dollar Index rose as the VIX declined, but these simultaneous moves alone cannot establish the cause of the stock market decline.

All Major Indexes Fall, With the Dow Posting the Largest Loss

All figures below are closing data from the U.S. regular session on August 6, 2026. Index levels and changes are measured in points, while percentage changes are measured in %.

The Russell 2000 ended the same session at 3,001.55 points, falling 17.64 points, or 0.58%. The Russell 2000’s percentage decline was 0.40 percentage points larger than that of the S&P 500.

Editor’s interpretation: The August 6, 2026, closing data show weakness across the broader market, but there was a substantial difference between the Nasdaq Composite’s 0.06% decline and the Dow Jones’s 0.85% drop. The fact that all four indexes fell therefore does not mean that every sector and stock was equally weak.

Only Microsoft Posts a Gain Above 2%

Microsoft, the strongest performer among the tracked stocks on August 6, 2026, closed the regular session at $499.86, rising $12.40, or 2.54%, from the previous close. Compared with the Nasdaq Composite’s 0.06% decline during the same session, the performance gap was 2.60 percentage points. Historical analysis is available through Microsoft closing data and the Microsoft stock hub.

Apple closed at $312.41 on August 6, 2026, up $1.41, or 0.45%, from the previous close. Meta also rose during the same session, gaining $1.13, or 0.19%, to $589.90. Nvidia, by contrast, fell $0.23, or 0.10%, to $218.99, while Amazon declined $0.39, or 0.14%, to $272.26. Apple closing data Apple stock hub Nvidia stock hub Amazon stock hub

Alphabet closed at $357.75 on August 6, 2026, down $4.68, or 1.29%, from the previous close. Tesla fell $2.02, or 0.63%, to $319.53 during the same session. Alphabet closing data Alphabet stock hub Tesla stock hub

Editor’s interpretation: The Nasdaq Composite’s limited 0.06% decline on August 6, 2026, cannot be attributed conclusively to any single stock. However, the closing data for the tracked stocks show Microsoft rising 2.54% while Alphabet fell 1.29%, confirming divergent performance among large technology stocks.

SanDisk Plunges as Treasury Yield and Dollar Rise Together

SanDisk closed at $1,258.58 on August 6, 2026, down $91.92, or 6.81%, from the previous close. It was the largest percentage decline among the tracked stocks, exceeding the Nasdaq Composite’s loss during the same session by 6.75 percentage points. Micron also fell, declining $11.72, or 1.31%, to $881.47. SanDisk closing data SanDisk stock hub Micron closing data Micron stock hub

Investopedia’s market report that day covered the declines in the major indexes and presented the weakness in SanDisk and Western Digital shares alongside quarterly revenue, profit, and market expectations. These were company-specific explanations reported by the publication; they do not mean that the closing data themselves prove why SanDisk fell 6.81% during the regular session on August 6, 2026.

The U.S. 10-year Treasury yield closed at 4.670% on August 6, 2026, up 0.053 percentage points from the previous close. The U.S. Dollar Index rose 0.273 points, or 0.27%, to 99.963 points during the same session. The VIX, by contrast, fell 0.70 points, or 4.43%, to 15.11 points.

Editor’s interpretation: Declining stock indexes, a rising long-term Treasury yield, a stronger U.S. Dollar Index, and a falling VIX occurred together on August 6, 2026. In particular, the VIX’s 4.43% decline despite the Dow Jones’s 0.85% drop makes it difficult to explain the day’s closing configuration solely through a risk-off narrative. This is an interpretation based on comparing closing data and does not imply a causal relationship among the indicators.

Three Items to Watch in the Next Regular Session

  1. Watch whether the 0.79-percentage-point gap between the Dow Jones, which fell 0.85% on August 6, 2026, and the Nasdaq Composite, which declined 0.06%, narrows during the next regular session.

  2. Watch whether Microsoft, which rose 2.54% on August 6, 2026, and SanDisk, which fell 6.81%, continue to move differently from the other tracked stocks and the Nasdaq Composite during the next regular session.

  3. Watch how the U.S. 10-year Treasury yield, which closed at 4.670% on August 6, 2026, the U.S. Dollar Index, which ended at 99.963 points, and the VIX, which fell to 15.11 points, move in combination with the stock indexes during the next regular session. These are closing-data observations, not predictions about the next session’s direction or judgments about buying or selling.
