Company snapshot — STMicroelectronics NV ADR

STM in five paragraphs: what it makes and sells, where it sits in the Closelook stack, who it is priced against, why we track it, what we watch. Research diary, not advice.

What it does
STMicroelectronics designs, manufactures and sells semiconductor products across analog, power and discrete, embedded processing, and radio-frequency segments. It makes power-management chips, MEMS sensors, silicon and silicon-carbide power devices, and microcontrollers used in automotive, industrial and personal-electronics equipment. It is headquartered in the Netherlands and sells across Europe, the Americas and Asia Pacific.
Where it sits in the stack
In our index, STM sits in Layer 4, Infrastructure, within the Power Semiconductors sleeve, alongside substrates, grid infrastructure and thermal management. This sleeve covers power-management chips, GaN and SiC devices, because every extra megawatt the AI build-out adds needs matching power semiconductors underneath it; STM is a constraint on how fast that power can be delivered into racks.
Who it is priced against
Closelook's peer group places it with the sleeve's power-semiconductor names — Texas Instruments, Monolithic Power Systems, ON Semiconductor, Allegro Microsystems and Renesas — grouped for their shared exposure to power delivery; Infineon is the additional name the market often sets alongside them.
Why Closelook tracks it
STM holds a seat in our index and in the Euro-AI 50, and it carries a Closelook score, a nightly composite across several modules; momentum reads as the strongest module and quality as the weakest. The diary has referenced it in the Daily Pulse, including once when power-delivery names for newer rack architectures were named as a driver of a monthly move.
What the diary watches
Whether power delivery per rack keeps rising with newer architectures, and whether that keeps drawing the power-semiconductor sleeve, STM included, into the same move together.

STMicroelectronics NV ADR (STM) trades on US exchanges in Switzerland, classified under Technology, and sits in Layer 4 of the build-out stack. Constituent of Rubin Build-Out 100 and Euro-AI 50.

The Closelook company score reads 45/100 composite (momentum 49, quality 20, valuation 41) across 7 modules — the full breakdown, chart structure and analog history load live above.
