Top Semiconductor Stocks Investors Are Watching in May: Nvida, AMD, Micron Lead

TLDR

• AI demand is driving a broad rally in semiconductor stocks, with the PHLX Semiconductor Index outperforming the S&P 500 by its widest margin in over a year
• Nvidia holds the strongest analyst ratings in the group with 48 buy ratings and zero sells
• AMD reported Q1 revenue of $10.25 billion with data-center revenue up 57%, triggering price target upgrades from at least 20 brokerages
• Micron had its best week since 2008, rising 30% over five sessions on AI memory demand
• ASML is the only stock in the group with sell ratings, with 2 sells alongside 21 buys

Artificial intelligence is still the biggest force in the stock market right now. Chip companies are at the center of that story, and five names keep coming up for investors watching the semiconductor sector in May 2026.

The PHLX Semiconductor Index recently outperformed the S&P 500 by its widest margin in more than a year. That rally has been broad, touching GPU makers, memory companies, chip equipment suppliers, and networking firms.

Here is a closer look at the five semiconductor stocks investors are watching most closely.

Nvidia

Nvidia is still the leader in AI chips. Its GPUs power the training and running of advanced AI models, and its software and networking ecosystem makes it more than just a hardware company.

NVIDIA Corporation, NVDA

Wall Street agrees. Nvidia has 48 buy ratings, 4 strong buys, 2 holds, and zero sell ratings according to MarketBeat data. That is one of the most one-sided analyst consensus readings in the market.

The main risk is valuation. The stock has already had a large run, and continued gains depend on whether earnings keep beating high expectations.

AMD

Advanced Micro Devices is the top challenger to Nvidia in AI chips. The company posted Q1 adjusted EPS of $1.37 on revenue of $10.25 billion, with data-center revenue jumping 57% year over year.

Advanced Micro Devices, Inc., AMD

AMD guided Q2 revenue to around $11.2 billion, above what analysts had expected. At least 20 brokerages raised their price targets after the earnings report.

Analyst ratings sit at 30 buys, 2 strong buys, and 12 holds with zero sells. The risk is that expectations have moved up quickly alongside the stock price.

Broadcom

Broadcom gives investors AI exposure beyond GPUs. The company is tied to custom AI chips, networking hardware, and cloud infrastructure spending by large tech companies.

Reports have linked Broadcom to custom AI chip work with OpenAI, though questions around financing and customer concentration have also surfaced. Analysts rate it at 27 buys, 2 strong buys, and 4 holds with zero sells.

Micron Technology

Micron is the memory play in this group. AI data centers require high-bandwidth memory, and Micron has been a direct beneficiary of that demand.

MarketWatch reported that Micron had its best week since 2008, climbing 30% over five trading sessions and surpassing JPMorgan in market value. Analysts have 30 buys, 5 strong buys, and 4 holds on the stock with zero sells.

The risk is that memory is historically a cyclical business, and pricing strength can reverse if supply increases.

ASML

ASML makes the lithography machines used to manufacture cutting-edge chips. Without ASML equipment, companies like Nvidia, AMD, and TSMC cannot produce the most advanced semiconductors.

That makes ASML a supply-chain essential rather than a direct chip seller. It carries 21 buys, 3 strong buys, 6 holds, and 2 sell ratings — the only stock in this group with any sell ratings. Export controls and large customer spending cycles are the key risks to watch.

Final Thoughts

The semiconductor sector is being driven by real demand, not just hype. AI data centers need chips, memory, and the machines to build them — and these five companies sit at the center of that. Analyst ratings across the group are broadly positive, though valuations have moved up sharply, so investors should weigh the risk alongside the opportunity.
