Advanced Micro Devices (AMD 5.54%) surged 5.7% Tuesday to close at $172.40, gaining ground despite a mixed Q2 earnings report. The stock saw a sharp spike in trading volume, with 94.4 million shares exchanged, nearly 80% above its three-month average of 53 million. AMD stock trades about 5.5% below its 52-week high of $182.50.

The broader market showed a split tone. The Nasdaq Composite climbed 0.4%, supported by strong performance in the semiconductor sector, while the S&P 500 slipped 0.1% amid more cautious trading in large-cap names.

AMD's peers also posted gains. Nvidia (NVDA 0.60%) rose 0.8% to $180.77, and Broadcom (AVGO 0.57%) added 0.7% to close at $303.76, as investors rotated back into chip stocks on optimism around potential U.S. tariff exemptions for domestic semiconductor manufacturers.

Despite a record $7.7 billion in second-quarter revenue, AMD's margins declined because of an $800 million inventory write-down tied to U.S. export restrictions. However, the company guided for third-quarter revenue of approximately $8.7 billion, easing concerns and reinforcing investor confidence. Analysts remain bullish on AMD's positioning in the AI accelerator and data center markets.
