How it trades on rate days beta 0.27 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 0.27 — shows only a loose link to bond moves for every 1% move in TLT (20+ year Treasuries), United Microelectronics moved 0.27% on average · correlation 0.04 · higher than 19% of US names
  • Beta, last 3 months 0.03 less 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.

How to use this chart

Toolbar

  • Range — 1M to MAX on daily closes. 1D/5D switch a US stock cell to 5-minute intraday bars; index and foreign cells fall back to 1M daily with a note.
  • Grid — 1×1 up to 2×2. Cells are synchronized: pan or zoom one and the others follow the same dates; the crosshair tracks across all of them. 4 INDICES loads Rubin · HALO · AEI · AW40 side by side.
  • Type / Scale — OHLC, line or area; linear or log price axis.

Picking a series

  • Tap the box in a cell's header to browse every Closelooknet series — headline indices, sub-indices, sectors, layers of all six families — plus the constituents.
  • Or type any ticker (NVDA, 7203.T, ASML.AS …) and press Enter — it charts in the cell straight from our data lake.

Studies

  • Overlays / Oscillators rows toggle the standard set (SMA, Bollinger, RSI, MACD …) per cell.
  • Levels (stock cells) draws the structure engine's support lines — regression bands, pivot cluster, SMA-200, the active fib zone.

Drawing

  • Tap a tool (Trend, Ray, H-Line, Fib, Channel, Rect, Note), then tap the chart once per point — the shape follows your finger or cursor between taps. The chart stops panning while a tool is armed; tap the tool again to release.
  • Drawings save per symbol in this browser and travel between the terminal and the asset page.
  • Delete key removes the selected drawing · Escape cancels a half-placed one · Clear wipes the symbol.

Wave counts

  • Wave places an Elliott count: tap the origin, then each wave end. Press Enter to stop early (inside wave 3 is fine) — dotted ghost targets sketch the remaining waves at guideline ratios.
  • On stocks the scanner's machine count appears automatically in grey — it is fully editable: drag any point, double-tap a label to remove it, Delete to dismiss it for good, Adopt to bring the machine's proposal back.
  • The sequence picker switches 1-5 / A-B-C / A-E / W-X-Y-Z; 1 2 3 cycles the degree; Subdiv starts a one-degree-smaller child count inside a wave.

Sharing

  • Card exports the cell as a branded PNG — chart, drawings and levels exactly as shown.
