How it trades on rate days

How MPWR has moved when long-dated Treasury yields rise — measured against TLT, the 20+ year Treasury fund.

  • Beta to long bonds, 1 year 0.06 — shows only a loose link to bond moves for every 1% move in TLT (20+ year Treasuries), Monolithic Power Systems Inc moved 0.06% on average · correlation 0.01 · higher than 12% of US names
  • Beta, last 3 months 0.07 about the same as over the year
  • On the 10 worst bond days −0.64% on average against −0.74% for the S&P 500 the 10 sessions of the past year in which TLT fell most, i.e. long yields rose most
  • Latest of those days −1.47% TLT −1.29% that day 2026-09-24

Daily total returns from the adjusted price series; a TLT down day is a day long yields rose. Beta = the average move of the name for a 1% move in TLT. Past sensitivity, not a forecast. An investment diary, not a recommendation.

Company snapshot — Monolithic Power Systems Inc

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

What it does
Monolithic Power Systems designs power-management chips: DC-to-DC converters, AC-to-DC circuits, driver MOSFETs and power-management ICs that regulate voltage inside servers, AI systems, memory, storage, networking and automotive equipment. It sells through distributors and resellers into storage and computing, enterprise data, automotive, communications, consumer and industrial markets. The company is based in West Palm Beach, Florida.
Where it sits in the stack
In our index, the Rubin Build-Out 100, Monolithic Power sits in Layer 4, Infrastructure, within the Power Semiconductors sleeve alongside substrates, grid equipment and thermal names. Every additional unit of AI compute needs matching voltage conversion, so it supplies a constraint the build-out cannot skip: the chips that step power down to what a processor or memory stack can use.
Who it is priced against
Closelooknet's peer group places it with the other power-semiconductor names in the Rubin sleeve — Texas Instruments, ON Semiconductor, STMicroelectronics, Allegro Microsystems and Renesas — on the reasoning that AI-driven power demand runs through all of them; the market also names Infineon Technologies as a comparable.
Why Closelooknet tracks it
It is a Rubin Build-Out 100 constituent and a Nasdaq-100 name, and it carries a Closelooknet score whose strongest module is quality and whose weakest is valuation. The diary has quoted it in the Daily Pulse, the Midday 10 and the Morning 10 when analog and storage names moved together against the broader market.
What the diary watches
Whether the analog and storage complex keeps trading as one block on down days, and whether power-semiconductor demand tracks the pace of new AI capacity as the diary expects.

Monolithic Power Systems Inc (MPWR) trades on US exchanges, classified under Technology, and sits in Layer 4 of the build-out stack. Constituent of Rubin Build-Out 100.

The Closelooknet company score reads 59/100 composite (momentum 63, quality 73, valuation 19) across 7 modules — the full breakdown, chart structure and analog history load live above.
