Why did NVDA move on Aug 27, 2025?

Nvidia (NVDA) moved in after-hours trading around 16:21 ET on August 27, 2025, following the release of its fiscal second-quarter 2026 earnings report. The company reported non-GAAP diluted EPS of $1.05 (or $1.08 GAAP), beating the consensus estimate of $1.01, on revenue of $46.7 billion, which also surpassed expectations of $46.0 billion. Despite the double beat and the announcement of an additional $60 billion share buyback authorization, the stock initially dipped in after-hours trading as investors reacted to a sequential slowdown in growth, a slight miss in data center revenue ($41.1 billion vs. $41.3 billion expected), and a lack of H20 chip sales to China.
