How it trades on rate days beta 0.29 to TLT · on the worst bond days it moved with the market

How it trades on rate days

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

  • Beta to long bonds, 1 year 0.29 — shows only a loose link to bond moves for every 1% move in TLT (20+ year Treasuries), ON Semiconductor Corporation moved 0.29% on average · correlation 0.04 · higher than 28% of US names
  • Beta, last 3 months 0.37 about the same as over the year
  • On the 10 worst bond days −0.67% 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 −1.28% 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 — ON Semiconductor Corporation

ON 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
ON Semiconductor designs power and sensing chips across three groups: power devices for converting and switching electricity, analog and mixed-signal parts for power management and connectivity, and image and depth sensors used in automation and robotics. Its customers span automotive, industrial and computing markets, including AI data-centre equipment. The company is based in Scottsdale, Arizona.
Where it sits in the stack
In our Rubin Build-Out 100 index, ON sits in Layer 4, Infrastructure, within the Power Semiconductors sleeve alongside power-management chips, GaN and SiC devices. Every additional megawatt the AI build-out needs must pass through power semiconductors like these, so ON is a supplier the infrastructure layer depends on as capacity scales.
Who it is priced against
Closelooknet's peer group places it with power-semiconductor names under the same sleeve — Texas Instruments, Monolithic Power Systems, STMicroelectronics, Allegro Microsystems and Renesas Electronics — because each supplies the power components the build-out's megawatt growth requires. The market also compares it with Infineon Technologies.
Why Closelooknet tracks it
ON holds a seat in the Rubin Build-Out 100 and carries a Closelooknet score, where capital allocation is its strongest module and momentum its weakest.
What the diary watches
The diary watches whether demand for power conversion in AI data centres offsets weaker momentum elsewhere in ON's chip lines.

ON Semiconductor Corporation (ON) 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 49/100 composite (momentum 38, quality 42, valuation 48) across 7 modules — the full breakdown, chart structure and analog history load live above.
