What Happened?

A number of stocks jumped in the afternoon session after Jensen Huang's (Nvidia's CEO) GTC Taipei keynote at Computex reframed how large and how long the AI chip cycle will run. 

The first announcement — Vera Rubin entering full production — confirmed the next wave of data center AI compute is now locked in. Vera Rubin, Nvidia's successor to Blackwell, delivers a 10x reduction in inference token cost and requires 4x fewer GPUs to train the same models. Thousands of Nvidia engineers were involved in its development, and system builders already in full-scale production include Dell, HPE, Lenovo, Supermicro, and IBM. That list is a read-through for the entire AI supply chain: every name on it needs more servers, more memory, more optical connectivity, and more chip equipment. 

The second announcement carried a different charge. Nvidia unveiled RTX Spark — an Arm-based AI PC chip co-developed with MediaTek — and Jensen Huang said Nvidia and Microsoft are going to "reinvent the PC." RTX Spark integrates a Blackwell GPU and a Grace CPU on a single package with 128GB of unified memory, capable of running 120-billion-parameter AI models locally without cloud connectivity. It launches later in the year on Windows PCs from Microsoft, Dell, HP, ASUS, Lenovo, and MSI.

The stock market overreacts to news, and big price drops can present good opportunities to buy high-quality stocks.

Zooming In On Allegro MicroSystems (ALGM)

Allegro MicroSystems’s shares are extremely volatile and have had 32 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 gained 9.8% on the news that Micron's UBS-led surge ignited a semiconductor rally. 

Stocks like Micron Technology (MU) and Advanced Micro Devices (AMD) were at the forefront, with Micron posting an impressive gain of 17.16% and AMD up by 5.68%. Broadcom (AVGO) and Intel (INTC) also had robust performances with increases of 4.84% and 1.72%. Iran-US peace progress and cooling Treasury yields amplified the move. GPU shipped enables more AI training and inference, which generates demand for more GPUs (Nvidia, AMD), more CPUs (AMD EPYC, Intel Xeon), more custom silicon (Broadcom TPUs, Marvell ASICs), and more memory (Micron). 

UBS's call that Micron has 100%+ upside on long-term supply contracts validated the structural thesis. AI demand isn't a cyclical bubble, it's a multi-year capacity buildout where the chip companies are supply-constrained. 

Adding to the momentum, analysts pointed to a cyclical recovery in key end markets and increased pricing power for chipmakers. According to a Bank of America note, core industrial and automotive markets "finally turned the corner," shifting from being headwinds during the recent inventory correction to providing cyclical tailwinds for the industry. This recovery in demand was supported by signs of strengthening pricing power. 

Reports indicated that major manufacturers like Texas Instruments were set to implement comprehensive price increases for certain products in 2026. This combination of recovering demand and the ability to raise prices suggests a healthy supply-demand balance, pointing to improved profitability for the sector.

Allegro MicroSystems is up 85.7% since the beginning of the year, and at $49.98 per share, it is trading close to its 52-week high of $51.37 from May 2026. Investors who bought $1,000 worth of Allegro MicroSystems’s shares 5 years ago would now be looking at an investment worth $1,875.
