What Happened?
A number of stocks jumped in the afternoon session after confidence in the artificial intelligence market was renewed, pushing both the S&P 500 and Nasdaq to new all-time intraday highs.
The rebound was led by chipmaker Nvidia, whose shares rose nearly 2% after its CEO confirmed that demand for computing has "gone up substantially" in recent months. These comments helped reassure the market that the AI boom is supported by genuine demand, calming fears that were sparked a day earlier by a report questioning the profitability of Oracle's cloud business. The rally was strong enough to put the information technology sector on pace for a fresh closing high. This upward momentum occurred despite potential headwinds from an ongoing U.S. government shutdown, which entered its second week.
The stock market overreacts to news, and big price drops can present good opportunities to buy high-quality stocks.
Among others, the following stocks were impacted:
Zooming In On Super Micro (SMCI)
Super Micro’s shares are extremely volatile and have had 81 moves greater than 5% over the last year. In that context, today’s move indicates the market considers this news meaningful but not something that would fundamentally change its perception of the business.
The previous big move we wrote about was 2 days ago when the stock gained 4.6% on the news that investor optimism rippled through the AI hardware sector as key chip supplier Advanced Micro Devices (AMD) announced a multiyear partnership to supply artificial intelligence chips to OpenAI.
The major agreement positioned AMD as a more forceful challenger in the AI chip market. Under the terms of the deal, AMD was set to provide OpenAI, the company behind ChatGPT, with its high-performance graphics chips for a massive AI infrastructure buildout. Analysts noted the partnership could yield tens of billions of dollars in annual revenue for AMD. This news created positive sentiment for server manufacturers like Super Micro, as a large-scale deployment of new AI chips was expected to drive significant demand for the specialized server systems the company builds.
Super Micro is up 93.8% since the beginning of the year, and at $58.23 per share, it is trading close to its 52-week high of $60.71 from July 2025. Investors who bought $1,000 worth of Super Micro’s shares 5 years ago would now be looking at an investment worth $21,090.
