How it trades on rate days

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

  • Beta to long bonds, 1 year 0.46 — shows only a loose link to bond moves for every 1% move in TLT (20+ year Treasuries), Axcelis Technologies Inc moved 0.46% on average · correlation 0.06 · higher than 38% of US names
  • Beta, last 3 months −1.71 less rate-sensitive lately than over the year
  • On the 10 worst bond days −1.41% 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 −1.93% 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 — Axcelis Technologies Inc

ACLS 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
Axcelis designs and builds ion implantation systems that introduce dopants into semiconductor wafers, a core step in chip fabrication, across high-energy, high-current and medium-current implanter lines. It also sells lifecycle support — used tools, spare parts, upgrades, maintenance and training — to extend equipment life for its customers. Its buyers are chip manufacturers, reached through a direct sales force across the United States, Europe and Asia. It is based in Beverly, Massachusetts.
Where it sits in the stack
In Rubin, our index of the AI build-out supply chain, Axcelis sits in Layer 6, Manufacturing Support, within the Fab Subsystems & Process Infra sleeve, which the diary groups with vacuum, gas-delivery and ultra-high-purity fluid systems that keep other tools running. Within that sleeve Axcelis is itself a constraint on how fast a fab can add front-end capacity, since wafers need implantation before they can move to later process steps.
Who it is priced against
Closelooknet's peer group places it with MKS Instruments, Advanced Energy Industries, Ebara and Horiba, grouped as the fab plumbing that the headline process tools depend on; the market also compares it with Applied Materials as a broader front-end equipment maker.
Why Closelooknet tracks it
It holds a seat in Rubin, our index of the AI build-out supply chain. It carries a Closelooknet score, with momentum the strongest module and valuation the weakest; the diary follows it as one of the front-end tool names rather than a chip maker.
What the diary watches
Whether orders for implantation tools recover as fabs resume front-end capacity expansion, since Axcelis's volume tends to move with that cycle rather than with chip demand directly.

Axcelis Technologies Inc (ACLS) trades on US exchanges, classified under Technology, and sits in Layer 6 of the build-out stack. Constituent of Rubin Build-Out 100.

The Closelooknet company score reads 40/100 composite (momentum 13, quality 44, valuation 35) across 7 modules — the full breakdown, chart structure and analog history load live above.
