Something happened in the stock market this week that has never happened before.
The Philadelphia Semiconductor Index, the benchmark that tracks the biggest chip stocks in America, just closed up for 18 straight trading days. That’s the longest winning streak in the index’s 32-year history. The previous record was 15 days, set back in 2014. The index is up roughly 40% during this run, on pace for its best month since February 2000.
If that last date gives you pause, it should. February 2000 was the peak of the dot-com bubble. So the question every investor has to ask right now is simple. Is this the beginning of a new era, or the end of an old one?
I’ve watched enough cycles to tell you the honest answer. It’s probably both. The AI buildout is real. Intel just crushed earnings. Micron is printing record revenue. Data center demand is not a rumor. But the math has gotten aggressive on some of these names, and that matters. Here are three I’m watching right now, with a clear eye on both the opportunity and the risk.
Intel (INTC)
Intel just had one of the cleanest earnings beats on Wall Street. The stock is trading around $81 today, up more than 21% on Q1 numbers that blew past expectations. Foundry revenue came in at $5.4 billion, up 20% from the prior quarter. June guidance of $14.3 billion in revenue beat consensus by over a billion dollars. The stock is now up roughly 240% year-to-date, trading near a 52-week high.
What’s driving it? The Trump administration took a direct equity stake in Intel last year, turning the federal government into a long-term partner. The CHIPS Act money is flowing. AI demand is showing up in the numbers. And the new leadership is starting to deliver on the foundry story that was all hope and no proof for the last two years.
Honest caution. Morningstar flags Intel as trading well above fair value after this run. At $81 per share, a lot of good news is priced in. If you didn’t catch the move from $20 last year, chasing the stock here is a different kind of bet. I’d rather wait for a pullback to the mid-$60s than pay today’s price. But the turnaround is real, and that alone is worth tracking.
Micron Technology (MU)
Micron is the purest play on AI memory in the market. Its high bandwidth memory chips go into every serious AI server built. Nvidia needs them. AMD needs them. Every hyperscaler building data centers needs them. Demand right now is greater than supply.
The stock is trading at a fresh all-time high today, around $496 and still climbing. Q1 revenue of $13.6 billion was up 57% year-over-year. Goldman Sachs has been raising its price target. This is the kind of momentum that either keeps going or snaps hard.
Here’s how I think about Micron. The structural tailwind is the strongest of any memory name. But memory is a cyclical business. Always has been. When supply finally catches up with demand, margins can compress in a hurry. If you own Micron, enjoy the run and consider taking some profits along the way. If you don’t, put it on your watchlist and wait for a correction. These rallies give you entry points. They always do.
Advanced Micro Devices (AMD)
AMD is the name that moved the most today. Shares jumped nearly 14% to around $347, up from the low $200s just a few months ago. Data center revenue hit $4.3 billion last quarter. The MI400 series AI chip is ramping for delivery later this year, and analysts expect AMD to ship roughly 258,000 units in 2026 at an average price near $31,000 each.
AMD has a real shot at capturing meaningful share in the AI accelerator market dominated by Nvidia. That doesn’t mean beating Nvidia. It means stealing 10 to 20% of a market that’s expanding fast enough to make both companies rich. Cloud inference workloads are the natural entry point, and AMD is positioning directly for that.
The risk is execution. AMD has missed timelines before. If the MI400 ramp slips into 2027 or the first customer wins go to Nvidia’s next generation chip instead, the stock will feel it. And at $347 after today’s jump, AMD is no longer the value play it was a month ago. The thesis is still intact, but the entry point matters. I’d prefer to add on weakness rather than chase here.
How to Think About This
An 18-day winning streak in a 32-year-old index is not normal. It doesn’t mean the rally is done, and it doesn’t mean you should sell everything tomorrow. It means you should be thoughtful about what you pay.
I’d treat all three names as long-term holdings, not short-term trades. If you already own them, congratulations. You caught the move. Trim into strength if you’re comfortable doing so. If you don’t own them, don’t feel pressure to buy today’s high. Markets give you better prices when everyone gets too excited. That pullback always comes. Your job is to be ready with a list when it does.
This list is a start.
