Despite beating earnings expectations, AMD shares declined in after-hours trading. The chipmaker reported a sequential quarterly revenue decline, causing investor concerns. This comes as the artificial intelligence trade faces scrutiny, with investors questioning high valuations. The company's Q4 2025 earnings per share came in at $1.53, exceeding estimates.

AMD's guidance for Q1 2026, projecting revenue between $9.50 billion and $10.10 billion, also factored into the stock's dip. While this indicates a year-over-year increase, it also suggests a quarter-over-quarter drop of about 5%. The data center segment remained strong, with record revenue.

Lisa Su, AMD's CEO, expressed optimism about business momentum. The company has been competing with Nvidia in the lucrative market for AI chips, which is currently a high-growth sector. The client and gaming segments also performed well.

Analysts are watching the AI sector closely, as high valuations and spending plans by major tech firms are under review. Investors will be keen to see if AMD can maintain its growth trajectory. The company's focus on data centers and AI accelerators will be key.
