How it trades on rate days beta 0.43 to TLT · on the worst bond days it fell more than the market

How it trades on rate days

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

  • Beta to long bonds, 1 year 0.43 — shows only a loose link to bond moves for every 1% move in TLT (20+ year Treasuries), Amkor Technology Inc moved 0.43% on average · correlation 0.05 · higher than 43% of US names
  • Beta, last 3 months 0.03 less rate-sensitive lately than over the year
  • On the 10 worst bond days −1.02% 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 −1.18% 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 — Amkor Technology Inc

AMKR 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
Amkor provides outsourced assembly and test services for semiconductor chips: it takes finished wafers from a fab, cuts them into dies, packages them, and tests the finished part before it ships to a customer. Its packaging methods cover flip-chip, wafer-level and system-in-package builds used in phones, computing, automotive and other electronics, and its test services check chips at wafer, package and system level. It works for chip designers, integrated device makers and foundries and is based in Tempe, Arizona.
Where it sits in the stack
In our Rubin Build-Out 100 index, Amkor sits in Layer 2, Fabrication, in the Foundry & Integration sleeve, alongside the firms that turn a design file into a working die. Amkor does the assembly and test step that follows wafer fabrication, so it is a customer of foundry capacity and a constraint on how quickly finished dies reach the packaging stage.
Who it is priced against
Closelooknet's peer group for this sleeve is Foundry & Integration, built around pure-play foundries and IDMs where capacity is the binding constraint; it lists Taiwan Semiconductor Manufacturing, ASE Industrial Holding, Tower Semiconductor and Globalfoundries alongside Amkor. The market also names JCET as a comparable outsourced-assembly competitor.
Why Closelooknet tracks it
Amkor is a constituent of the Rubin Build-Out 100 and carries a Closelooknet score, where the balance-sheet module reads strongest and momentum weakest. Our market-structure work has used it to show why the standard semiconductor bucket mixes unlike businesses together, and the Morning 10 has scanned it inside a semiconductor support cluster with ASML and ASM.
What the diary watches
The diary watches whether advanced packaging demand tied to AI chip stacks feeds through into Amkor's order book, and whether the momentum reading recovers from its current weak state.

Amkor Technology Inc (AMKR) trades on US exchanges, classified under Technology, and sits in Layer 2 of the build-out stack. Constituent of Rubin Build-Out 100.

The Closelooknet company score reads 42/100 composite (momentum 22, quality 33, valuation 47) across 7 modules — the full breakdown, chart structure and analog history load live above.
