How it trades on rate days

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

  • Beta to long bonds, 1 year −0.45 — shows only a loose link to bond moves for every 1% move in TLT (20+ year Treasuries), Ambarella Inc moved −0.45% on average · correlation −0.06 · higher than 4% of US names
  • Beta, last 3 months −1.18 less rate-sensitive lately than over the year
  • On the 10 worst bond days +1.93% 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 +3.31% 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.

AMBA 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
Ambarella designs low-power system-on-chip semiconductors and software for edge and physical artificial intelligence, combining vision processing, image and audio processing and system control on a single chip. Its lineup includes central domain controllers, CVflow processors, AI neural processors, vision SoCs, radars and serializer/deserializer chips, sold into automotive, security-camera, IoT and related markets through direct sales and distributors. It is headquartered in Santa Clara, California, and trades in the United States.
Where it sits in the stack
Ambarella carries no seat in Rubin, our index for the AI build-out; it sits in the semiconductor sleeve of our wider universe, classified as a chip-design house making embedded vision and AI processors for edge devices rather than data-centre accelerators.
Who it is priced against
Closelooknet's peer group for this name has not been set. The market commonly compares it with other edge-vision and embedded-AI chip designers such as Synaptics.
Why Closelooknet tracks it
Ambarella holds no seat in any Closelooknet index, and no Closelooknet score has started to build for it; the diary has not yet quoted it in the Morning 10 or the Weekly Ten.
What the diary watches
Closelooknet watches whether the recent cut to analyst price targets and the stock's distance below its moving averages reflect softer demand from automotive and security-camera customers, or a wider re-rating of edge-AI chip designers.
