AMD vs QCOM — which stock performed better?

Advanced Micro Devices, Inc. (AMD) versus QUALCOMM Incorporated (QCOM), Information Technology, on 2026-08-05.

Result

QUALCOMM Incorporated (QCOM) performed better on 2026-08-05. AMD moved -8.400%, QCOM moved -3.310%.

Why these two companies

AMD reports its second-quarter 2026 results after the closing bell on Tuesday, August 4, 2026, meaning the market's reaction to those numbers will define Wednesday, August 5's session for the stock. That report lands into a chip sector already on edge after QCOM's own July 29, 2026 earnings sparked a sharp guidance-driven selloff, making this a head-to-head test of two semiconductor bellwethers navigating the same AI-demand debate from very different starting points.

The research

AMD designs computer chips used in gaming PCs, laptops, and the powerful servers that run AI systems, competing head-to-head with Nvidia in the booming AI data-center market. QUALCOMM makes the chips that power most Android smartphones and is also pushing into car technology and AI hardware for data centers, trying to reduce how much it depends on phones.

One reason to like AMD going into this matchup is its data-center business, which has been growing quickly as companies keep buying chips to build AI systems. One reason to like Qualcomm is that its automotive and other non-phone businesses just hit record revenue, showing its diversification plan is gaining real traction even while phone chip sales slip.

Something to keep in mind for AMD: its stock has already climbed a lot this year, so investors expect a lot from its results, and any disappointment on future guidance can hit the stock hard even if the current quarter looks fine. Something to keep in mind for Qualcomm: it already reported its results a week earlier, and its stock is still well off its highs after the company gave a weaker profit outlook, so its next big move will likely take more time to unfold.

Because AMD's results land right before this matchup's trading day begins, this game is unusually tied to a single overnight event, while Qualcomm heads into the same day without a similar scheduled trigger.
