In the US regular session on August 4, 2026, the Nasdaq Composite gained 2.59%, posting the strongest close among the major indexes. Among the stocks tracked, SanDisk surged 10.84% and Micron jumped 7.62%, while Amazon and Meta declined, moving against the broader index rally. Another notable feature of the closing data was that the VIX also rose 3.91% even as all the stock indexes advanced.

The Russell 2000 rose 1.85% to 3,036.98 points on August 4, 2026, while the Dow Jones gained 1.71% to 54,085.88 points. Both large-cap and small- and mid-cap indexes advanced, but the gap between the indexes’ gains was as wide as 0.88 percentage points on August 4, 2026.

Yahoo Finance’s market coverage that day also reported that the Nasdaq Composite led the rally. This characterization is directionally consistent with the regular-session closing data from August 4, 2026, but the report’s wording alone cannot establish the direct cause of each index’s gain.

Editor’s interpretation: The closing figures on August 4, 2026, show relative strength in technology stocks alongside gains in both large-cap and small- and mid-cap indexes. However, the fact that all four indexes rose does not itself prove that any particular news or economic indicator caused the gains.
SanDisk and Micron Surge, While Amazon and Meta Move the Other Way
SanDisk, which posted the largest gain among the stocks tracked on August 4, 2026, surged 139.59 dollars, or 10.84%, from the previous close to finish the regular session at 1,427.62 dollars. That was 8.25 percentage points higher than the Nasdaq Composite’s 2.59% gain on the same trading day. Historical analysis of the individual stock is available through SanDisk closing data and the SanDisk stock hub.
Micron closed at 892.67 dollars on August 4, 2026, rising 63.17 dollars, or 7.62%, from the previous close. Its outperformance relative to the Nasdaq Composite was 5.03 percentage points on the same trading day. Nvidia also advanced, gaining 5.30 dollars, or 2.56%, to close at 211.94 dollars, but its percentage gain was 0.03 percentage points below the Nasdaq Composite’s.

By contrast, Amazon closed at 277.42 dollars on August 4, 2026, falling 6.60 dollars, or 2.32%, from the previous close. Meta also declined on the same trading day, losing 2.30 dollars, or 0.39%, to close at 587.94 dollars. Both stocks finished in the opposite direction on a day when the Nasdaq Composite rose 2.59%. The gap versus the Nasdaq Composite’s return was 4.91 percentage points for Amazon and 2.98 percentage points for Meta. Related analysis is available through Amazon closing data and the Amazon stock hub, as well as Meta closing data and the Meta stock hub.
Among the other stocks tracked on August 4, 2026, Apple rose 1.96% to 309.38 dollars, Tesla gained 1.64% to 327.35 dollars, Alphabet advanced 1.11% to 377.65 dollars, and Microsoft climbed 1.06% to 492.81 dollars. All four stocks gained, but each underperformed the Nasdaq Composite’s 2.59% advance on the same trading day. Apple stock hub Tesla stock hub Alphabet stock hub Microsoft stock hub
Editor’s interpretation: Although the technology-heavy index rose sharply on August 4, 2026, the direction and magnitude of moves among the stocks tracked were not uniform. SanDisk’s and Micron’s surges, together with Amazon’s and Meta’s declines, show substantial company-level divergence, but closing data alone cannot identify the specific cause of each stock’s move.
Oil and Yields Fell as the VIX Rose
WTI crude oil closed at 75.37 dollars per barrel on August 4, 2026, down 4.97 dollars per barrel, or 6.19%, from the previous close. The US 10-year yield ended the same trading day at 4.627%, down 0.059 percentage points from the previous close. Stock indexes rose as oil prices and long-term yields fell, but these simultaneous moves alone do not establish that declines in oil or yields caused stocks to rise.

Schwab’s early-session report cited strong results from Caterpillar and Palantir, along with hopes for progress toward peace, as factors behind the stock market’s rise at that time. That was the report’s interpretation early in the session and does not prove the direct cause of the index and individual-stock moves through the regular-session close on August 4, 2026. Original Schwab early-session report
The VIX rose 0.62 points, or 3.91%, from the previous close to 16.48 points on August 4, 2026. Because the VIX advanced even as all the major stock indexes rose on the same trading day, the closing data did not show the typical combination of rising stock prices and a declining volatility index. VIX closing data
Editor’s interpretation: On August 4, 2026, stock indexes rose, WTI crude oil and the US 10-year yield fell, and the VIX increased. This combination shows that the day’s market activity is difficult to explain with a single variable, but it does not prove causation among the indicators.
Three Items to Watch in the Next Regular Session
-
Watch whether the large moves in SanDisk and Micron, which rose 10.84% and 7.62%, respectively, on August 4, 2026, narrow in the next regular session and how their performance gap versus Nvidia, which gained 2.56% on the same trading day, changes.
-
Watch whether Amazon and Meta, which declined 2.32% and 0.39%, respectively, as the Nasdaq Composite gained 2.59% on August 4, 2026, continue to move in a different direction from the technology-heavy index in the next regular session.
-
Watch how WTI crude oil, which closed at 75.37 dollars per barrel on August 4, 2026, the US 10-year yield, which ended at 4.627%, and the VIX, which closed at 16.48 points, move in relation to the stock indexes in the next regular session. These are items for observation, not predictions about the next regular session’s direction or judgments about buying or selling.
