On July 31, Advanced Micro Devices rose 3.01% in after-hours trading, trading at $499.9/share, with turnover of $855 million.

On the news front, blowout earnings results from Microsoft, Lam Research, and Samsung reignited the AI chip trade, lifting semiconductor stocks broadly. The Philadelphia Semiconductor Index surged over 7% during the regular session, with Lam Research up over 20%, Applied Materials and ALAB up over 13%, and Micron Technology up nearly 12%. Additionally, Susquehanna raised its price target on AMD from $450 to $500, maintaining a positive rating. According to FactSet, AMD's mean analyst target price stands at $573.38.

The rally follows a sharp correction earlier in the week triggered by systemic selling pressure after the IPO of Chinese DRAM giant CXMT and profit-taking ahead of AMD's August 4 earnings report. Analysts note that after sustained deleveraging and position clearing, the AI semiconductor supply chain saw a structural rebound. Market consensus expects AMD to report quarterly revenue of $11.278 billion, representing approximately 52% year-over-year growth.
