How it trades on rate days

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

  • Beta to long bonds, 1 year 0.65 — shows only a loose link to bond moves for every 1% move in TLT (20+ year Treasuries), Rambus Inc moved 0.65% on average · correlation 0.08 · higher than 66% of US names
  • Beta, last 3 months 1.35 more rate-sensitive lately than over the year
  • On the 10 worst bond days −0.37% 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 +1.04% 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 — Rambus Inc

RMBS 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
Rambus designs semiconductor products, chiefly memory interface chips for DDR5 and DDR4 systems, and licenses silicon intellectual property for interface and security functions used in AI, data-centre, government and automotive chips. It sells through direct sales and distributors to memory module makers, OEMs, hyperscalers and chip makers, and holds a portfolio of patents covering memory architecture, high-speed links and security technology. Rambus is based in San Jose, California.
Where it sits in the stack
Rambus does not hold a seat in our Rubin index, so it sits within the semiconductors sector of our universe, in the chip IP and memory interface sleeve that supplies both memory makers and chip designers rather than owning fabrication itself.
Who it is priced against
Closelooknet's peer group data holds no formal comparison set for Rambus; a name the market commonly places beside it is Synopsys, which also licenses interface intellectual property alongside tool sales.
Why Closelooknet tracks it
Rambus does not currently sit in any of our indices and carries no Closelooknet score, so its module ratings are still being built; the diary has not yet recorded any quotes for it.
What the diary watches
Whether demand for DDR5 memory interface chips and security IP licensing keeps pace with memory makers' shipments, which would show up first in Rambus's product mix.
