How it trades on rate days

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

  • Beta to long bonds, 1 year 0.48 — shows only a loose link to bond moves for every 1% move in TLT (20+ year Treasuries), Tower Semiconductor Ltd moved 0.48% on average · correlation 0.06 · higher than 51% of US names
  • Beta, last 3 months 0.98 more rate-sensitive lately than over the year
  • On the 10 worst bond days −1.66% 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 −5.74% 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 — Tower Semiconductor Ltd

TSEM 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
Tower Semiconductor is an independent foundry that manufactures chips for other companies from their design files rather than designing end products itself. It focuses on customisable process technologies such as analogue and mixed-signal circuits, radio-frequency chips, silicon photonics, CMOS image sensors and power-management devices rather than the smallest transistor geometries. Its customers are integrated device makers and fabless companies serving consumer electronics, communications, automotive, industrial and medical markets. It is headquartered in Migdal Haemek, Israel.
Where it sits in the stack
In our Rubin Build-Out 100 index, Tower sits in Layer 2, Fabrication, within the Foundry & Integration sleeve — foundries and integrated device makers that turn design files into working dies, where capacity is the binding constraint. Tower is a customer of the equipment and materials layers above it and itself a constraint on capacity for the specialty analogue, RF and sensor chips it makes.
Who it is priced against
Its Closelooknet peer group is the Rubin Build-Out 100's Foundry & Integration sleeve, grouped because these firms turn design files into working dies and capacity is the constraint; it sits alongside Taiwan Semiconductor Manufacturing, ASE Industrial Holding, Amkor Technology and Globalfoundries. The market also names United Microelectronics as a comparable specialty and mature-node foundry.
Why Closelooknet tracks it
Tower is a constituent of the Rubin Build-Out 100. It carries a Closelooknet score, with momentum the strongest module and valuation the weakest.
What the diary watches
The diary watches whether specialty foundry order flow from analogue, RF and image-sensor customers strengthens as the AI build-out draws demand toward general capacity.

Tower Semiconductor Ltd (TSEM) trades on US exchanges in Israel, and sits in Layer 2 of the build-out stack. Constituent of Rubin Build-Out 100.
