How it trades on rate days beta 0.49 to TLT · on the worst bond days it held up better than the market

How it trades on rate days

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

  • Beta to long bonds, 1 year 0.49 — shows only a loose link to bond moves for every 1% move in TLT (20+ year Treasuries), United Microelectronics moved 0.49% on average · correlation 0.07 · higher than 51% of US names
  • Beta, last 3 months 1.46 more rate-sensitive lately than over the year
  • On the 10 worst bond days +0.89% 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 −2.35% 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 — United Microelectronics

UMC 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
United Microelectronics runs semiconductor wafer foundries, making chips to order for other companies rather than designing its own products. It offers circuit design support, mask tooling, wafer fabrication, and assembly and testing, serving communication, consumer electronics and computing customers. It is headquartered in Hsinchu City, Taiwan, and also runs operations across other parts of Asia, the United States and Europe.
Where it sits in the stack
United Microelectronics has no seat in our index. It sits in the foundry sleeve of the semiconductor universe, alongside contract manufacturers that fabricate chips designed by fabless customers rather than building their own products.
Who it is priced against
Closelooknet's peer group places it with the foundries — Taiwan Semiconductor Manufacturing, Intel, Samsung Electronics and Globalfoundries — the set the market prices contract chipmaking against.
Why Closelooknet tracks it
It carries no index seat and no Closelooknet score. The diary has quoted it once, in a dossier on the AI chip build-out, noting that automotive and industrial chip oversupply was squeezing margins at United Microelectronics and other legacy foundries.
What the diary watches
Whether oversupply in automotive and industrial chip demand keeps weighing on legacy foundry margins, which is what the diary watches for names like this one.
