Jim Cramer’s 11 Stock Calls Including Marvell and Trane, and Caution About Overhyped AI Stocks

In this article, we will look at Jim Cramer’s Mad Money stock calls as he urged investors to exercise caution when it comes to red-hot AI stocks. The host of CNBC’s Mad Money said Thursday that while he has no issue with stocks surging because of shortages, the trading action surrounding Cerebras Systems left him uneasy.

We had this IPO today… Cerebras, priced at $185. The stock opened at $350, instantly making it worth $17 billion on a fully diluted basis. Then it goes all the way up to $386, before closing at $311. Now, there is a word for that, that word is fanciful because it was fanciful to pay that much the whole time… Now, it doesn’t have to be this way, people. Perhaps there are people who will say, look, I lost so much money when the IPO market got too hot in 2021 or 2014 or when it was totally overwhelmed in 2000. But my fear is that was now too long ago, and there’re just not enough losers from then who know not to repeat those mistakes. Maybe we just have to live through it again. I’m trying to stop it.

It is worth noting that Cramer said that there are AI stocks like Cisco and NVIDIA that deserve the hype. He also said that while he has long maintained that if he ever witnessed this type of extreme enthusiasm return to the market, he would “scream from the rafters,” he would tell investors that it is necessary to pause the nonstop praise surrounding overheated sectors and remind investors that these stories can end badly. He continued to say that he knows that he said that he would urge people to stay disciplined and take the time to understand what these companies actually do, as well as why certain valuations may not make sense, but he added:

Here’s the bottom line: I don’t mind stocks that go up huge on shortages. I don’t think Micron, or Sandisk, or Western Digital, or even HBM chips from SK Hynix are overvalued, provided the Chinese don’t flood our markets with cheap memory. Cisco, NVIDIA, fine with me, but Cerebras, it’s like a Sondheim play, Send in the Clowns, because today that’s exactly what happened.

Jim Cramer’s 11 Stock Calls Including Marvell and Trane, and Caution About Overhyped AI Stocks

11. BillionToOne, Inc. (NASDAQ:BLLN)

BillionToOne, Inc. (NASDAQ:BLLN) was among Jim Cramer’s Mad Money stock calls as he urged investors to exercise caution when it comes to red-hot AI stocks. Toward the end of the lightning round, a caller sought Cramer’s opinion on the stock, and he commented:

We like BillionToOne. We looked at it, we thought the name was so silly… But it’s a real company… That’s going to be very good. I say buy it.

BillionToOne, Inc. (NASDAQ:BLLN) develops precision molecular diagnostics using a platform that counts DNA molecules to improve disease detection. The company’s tests include non-invasive prenatal screening and liquid biopsies to detect and monitor cancer mutations. Cramer was bullish on the stock when a caller inquired about the stock during the April 27 episode, as he commented:

We looked into BillionToOne. We think it’s a really good diagnostic company. Now, the diagnostic companies themselves have been going down, whether it be Becton, Dickinson, whether it be Abbott Labs, they’ve not been working. That said, this stock never ran to begin with. I think BillionToOne’s a winner.

10. Design Therapeutics, Inc. (NASDAQ:DSGN)

Design Therapeutics, Inc. (NASDAQ:DSGN) was among Jim Cramer’s Mad Money stock calls as he urged investors to exercise caution when it comes to red-hot AI stocks. A caller asked for Cramer’s thoughts on the company, and here’s what he had to say:

Pure spec, pure spec. Understand, you can lose everything, or you can double on that one. I don’t know which it’s going to be. That’s the problem.

Design Therapeutics, Inc. (NASDAQ:DSGN) is a clinical-stage biopharmaceutical company that develops small-molecule drugs to treat inherited genetic diseases caused by nucleotide repeat expansion. The company uses its proprietary platform, GeneTAC, to create potential treatments for conditions such as Friedreich’s Ataxia, Huntington’s Disease, and other progressive neuromuscular and neurodegenerative disorders.

9. Wynn Resorts, Limited (NASDAQ:WYNN)

Wynn Resorts, Limited (NASDAQ:WYNN) was among Jim Cramer’s Mad Money stock calls as he urged investors to exercise caution when it comes to red-hot AI stocks. A caller asked for Cramer’s take on the company, and he replied:

Yeah, they got that, you know, they got a problem over there in the Gulf. They got this big… deal that they spent a lot of money on, and I gotta hold off for now. I gotta wait to see what happens in that area.

Wynn Resorts, Limited (NASDAQ:WYNN) designs and operates luxury integrated resorts that include casino spaces, high-end hotel accommodations, and diverse entertainment attractions. These properties offer a variety of amenities, including fine dining, retail shops, convention facilities, and specialized leisure experiences like spas and nightclubs. During the episode aired on July 14, 2025, a caller inquired about the stock, and Cramer replied:

Oh, I think WYNN, you know, we were, we were at Wynn earlier this year, and I was very worried about China. I still am, but my, they’ve got a good thing going. Craig Billings is such a good manager. He’s actually terrific, and I’m glad to see that stock is finally starting to move. It’s still very inexpensive on a PE basis.

It is worth noting that since the above comment was aired, the company’s stock is down by nearly 14%.

8. Silicon Motion Technology Corporation (NASDAQ:SIMO)

Silicon Motion Technology Corporation (NASDAQ:SIMO) was among Jim Cramer’s Mad Money stock calls as he urged investors to exercise caution when it comes to red-hot AI stocks. When a caller asked about the stock, Cramer stated:

That is called SIMO… And we like SIMO. I know it’s moved a lot. So what you do in these is you buy some, and then you wait for a pullback. But you gotta put some on, and I think it’s a good call by you.

Silicon Motion Technology Corporation (NASDAQ:SIMO) develops and markets NAND flash controllers and specialized storage solutions for various applications, including computing, enterprise data centers, and mobile devices. Heartland Advisors stated the following regarding Silicon Motion Technology Corporation (NASDAQ:SIMO) in its Q1 2026 investor letter:

An example is Silicon Motion Technology Corporation (NASDAQ:SIMO). A year ago, shares of the leading maker of memory components used in PCs, smartphones, data centers, and industrial and auto applications sold off amid a variety of concerns. They included tariffs, consumer spending worries, and questions over whether investors might be overestimating the capex needs of large-scale cloud service providers known as hyperscalers. At the time, we remained committed to the stock because we believed the company was in the early days of a re-rating process, as SIMO had been making a push away from trailing-edge, lower-margin consumer electronics into higher-margin, leading-edge applications driven by hyperscaler demands.

What a difference a year makes. In the first quarter, the stock was a contributor to our outperformance, as consumer spending has held up and hyperscalers continue to indicate robust datacenter capex growth. In their fourth-quarter conference call, management reiterated the firm’s outlook for their PC and smartphone end markets and the growth prospects for their data center storage components, which are expected to drive margins substantially higher.

Yet in our opinion, SIMO remains meaningfully undervalued versus our current price target. The stock currently trades at $117, but we believe the company should be valued at $185. That’s based on a multiple of 15X EBITDA plus an anticipated $160 million cash settlement from SIMO’s ongoing arbitration with MaxLinear surrounding the termination of a proposed merger agreement more than two years ago.

7. Trane Technologies plc (NYSE:TT)

Trane Technologies plc (NYSE:TT) was among Jim Cramer’s Mad Money stock calls as he urged investors to exercise caution when it comes to red-hot AI stocks. Cramer highlighted the company’s recent quarterly earnings result, as he said:

This market is full of industrials that have caught fire because they own a piece of that great data center build-out. Take Trane Technologies, TT, the climate control company with a stock that’s up nearly 24% for the year. Now, a good part of that’s because it prevents these warehouses from overheating. A little over two weeks ago, Trane reported a healthy top and bottom line beat with its backlog up a staggering 30% year over year, commercial HVAC bookings in the Americas up 40%, applied equipment orders surging 160%. The whole business is thriving, but that data center side is really on fire, one reason why management raised their full-year forecast convincingly.

Trane Technologies plc (NYSE:TT) manufactures and services heating, ventilation, air conditioning, and refrigeration systems. The company’s business includes providing energy management solutions, building automation, and aftermarket parts.

6. Marvell Technology, Inc. (NASDAQ:MRVL)

Marvell Technology, Inc. (NASDAQ:MRVL) was among Jim Cramer’s Mad Money stock calls as he urged investors to exercise caution when it comes to red-hot AI stocks. A caller inquired if Cramer still likes the company, and in response, he said:

Oh yeah. Marvell’s, that’s Matt Murphy. He’s doing an amazing job. He bought that optical business. He’s really crushing it. I mean, you know, if like, if you want to look at Marvell versus say what was being hyped today, Marvell’s so dramatically cheaper, and it hit a 52-week high today. It can go higher. Remember, Matt came on the show when he bought like a ton at 70, and he was really upset. Remember? He came on, he said, listen, I am the signal, not the noise. Well, he just, he gave you almost a triple.

Marvell Technology, Inc. (NASDAQ:MRVL) develops semiconductor solutions for data infrastructure, including system-on-a-chip designs, processors, and networking and storage products. During the April 28 episode, a caller highlighted their purchase of 300 shares of the company at $85 three months earlier and their sale of half of them at $150. When they asked for Cramer’s advice, he replied:

You’re playing with the house’s money, my friend. Here’s what you do: You let it run. I think that you’ve got a total winner in Marvell, and you know what? You’re not going to lose. What a great position, you’re playing with the house’s money. Let it run. If it gets to $200, maybe take a little off.
