Why Did AMD Stock Jump?
AMD stock rose 9.9% on September 21, 2026, following a report of planned 10% price increases for its chips due to higher wafer costs. The company's gross margin has been rising, reaching 53% over the last year. AMD's P/E ratio is 155.2, significantly higher than the S&P 500's 21.7. Management expects data center revenue to more than double in 2027, but the price increase's impact on profit remains uncertain.
