Why AMD (AMD) Shares Are Sliding Today

What Happened?

Shares of computer processor maker AMD (NASDAQ:AMD) fell 5.3% in the afternoon session after the company was downgraded by Seaport Research due to concerns about slowing growth in its artificial intelligence (AI) business. The investment firm lowered its rating on the chipmaker to Neutral from Buy, with no price target, based on recent supply chain checks. These checks suggested slowing growth and difficulty in expanding orders for its AI accelerator business. 

Adding to the negative sentiment, New Street also adjusted its price target on AMD, cutting it to $150 from $230. Broader market pressures also weighed on the stock, as the U.S. administration announced it would impose tariffs on semiconductor imports from companies not shifting production to the U.S., creating further uncertainty for the industry. 

Separately, rival Broadcom confirmed a significant partnership with OpenAI (speculated), fueling concerns about intensifying competition in the artificial intelligence hardware market. Broadcom announced a $10 billion custom chip deal with OpenAI, a move that highlights a broader trend of major tech companies developing their own processors to cut costs and fine-tune AI performance. This strategy is also being pursued by Alphabet, Amazon, and Meta Platforms.

What Is The Market Telling Us

AMD’s shares are very volatile and have had 22 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 7 days ago when the stock dropped 3.1% on the news that stocks in the semiconductor sector pulled back triggered by a weak forecast from peer chipmaker Marvell Technology. 

Marvell's disappointing outlook, which it attributed to a slowdown in its custom AI chip business, soured investor sentiment across the industry. The news put pressure on the entire semiconductor sector, with AMD and other major chipmakers like Nvidia also seeing notable drops. The downturn was also influenced by some investors apparently locking in recent gains from the popular "AI trade," which has driven much of the market's recent performance. This profit-taking, combined with Marvell's cautious guidance, contributed to the negative pressure on chip stocks during the session.

AMD is up 26.7% since the beginning of the year, but at $152.80 per share, it is still trading 17.1% below its 52-week high of $184.42 from August 2025. Investors who bought $1,000 worth of AMD’s shares 5 years ago would now be looking at an investment worth $1,942.

Today’s young investors won’t have read the timeless lessons in Gorilla Game: Picking Winners In High Technology because it was written more than 20 years ago when Microsoft and Apple were first establishing their supremacy. But if we apply the same principles, then enterprise software stocks leveraging their own generative AI capabilities may well be the Gorillas of the future. So, in that spirit, we are excited to present our Special Free Report on a profitable, fast-growing enterprise software stock that is already riding the automation wave and looking to catch the generative AI next.
