Nvidia surges 8.74%, while Tesla and Microsoft also rise
Nvidia closed the regular session on August 27, 2026, at $227.98, up $18.32, or 8.74%. Its intraday high was $230.47, its low was $220.90, and volume was 293,335,993 shares. This was the largest closing percentage gain among the tracked stocks and substantially exceeded the Nasdaq Composite’s 1.57% gain. However, closing moves on the same day alone cannot establish that Nvidia’s rise caused the index gain. See Nvidia closing data and the Nvidia stock hub for continuing historical analysis.
Tesla finished the same trading day at $354.81, up $8.99, or 2.60%. Its intraday high and low were $355.74 and $345.45, respectively, and volume was 29,902,179 shares. Microsoft closed the regular session at $505.06, up $8.69, or 1.75%, with volume of 27,342,405 shares. See Tesla closing data and the stock hub, as well as Microsoft closing data and the stock hub.
News reports that day cited Nvidia’s earnings as a backdrop for the stock market’s rise. This is the interpretation in the Barron’s article and the Schwab market article; the closing data in this briefing alone cannot verify or establish that explanation as a causal relationship.
Amazon, Meta, and Alphabet move opposite to index gains
Amazon closed the regular session on August 27, 2026, at $256.26, down $4.02, or 1.54%. Its intraday high was $259.66, its low was $255.02, and volume was 35,599,961 shares. The same-day rise in the S&P 500 and Nasdaq Composite and Amazon’s closing decline are concurrent changes only; they cannot be used to determine the cause of the overall market move. See Amazon closing data and the Amazon stock hub.
Meta closed at $571.10, down $5.04, or 0.87%. Its intraday high was $588.39, its low was $567.62, and volume was 15,036,677 shares. Alphabet also finished the regular session at $340.65, down $1.35, or 0.39%. Historical analysis for each stock is available through Meta closing data and the stock hub, as well as Alphabet closing data and the stock hub.
Semiconductor-related tracked stocks also showed closing moves different from Nvidia’s. Micron closed August 27, 2026, at $935.39, down $3.01, or 0.32%, while SanDisk closed at $1,484.95, down $14.42, or 0.96%.

10-year yield and WTI rise as VIX declines

Changes in interest rates, oil prices, the VIX, and stock indexes were all concurrent changes based on August 27, 2026, closing data; the figures alone cannot determine one another’s causes. Refer to WTI crude oil closing data and USD/KRW data.
