How it trades on rate days

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

  • Beta to long bonds, 1 year 0.16 — shows only a loose link to bond moves for every 1% move in TLT (20+ year Treasuries), Sandisk Corp moved 0.16% on average · correlation 0.01 · higher than 18% of US names
  • Beta, last 3 months 0.45 more rate-sensitive lately than over the year
  • On the 10 worst bond days −0.44% 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 −3.47% 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 — Sandisk Corp

SNDK 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
Sandisk designs and sells NAND flash storage: solid-state drives for PCs and consoles, and embedded flash for phones, tablets, wearables, cars and industrial gear. It also makes removable cards, USB drives, wafers and components, sold mainly to computer makers, cloud providers and retailers. It is based in Milpitas, California.
Where it sits in the stack
In Rubin, our index of the AI build-out supply chain, Sandisk sits in Layer 3, Assembly & Test, in the HBM Memory sleeve, though the diary notes storage is being split into its own sub-index at the next reconstitution. Its NAND dies make it a customer of the wafer-processing layer above it, and its output is a constraint on how much bulk storage capacity the build-out can add alongside compute.
Who it is priced against
Closelooknet's peer group for this name is built on NAND and storage, curated as who the market prices it against: Micron, Western Digital, Seagate and SK Hynix; Samsung is the other name the market often adds to that set.
Why Closelooknet tracks it
It holds a seat in the Rubin Build-Out 100 and in the Nasdaq-100, and it carries a Closelooknet score, with quality the strongest module and valuation the weakest. The diary has flagged it in a Situational Awareness report and named it inside the Midday 10 and Morning 10 chip-and-memory sorts.
What the diary watches
The diary watches whether NAND storage starts showing the same supply strain as high-bandwidth memory as the build-out scales, and whether splitting storage into its own sub-index changes how this name is read against its peers.

Sandisk Corp (SNDK) trades on US exchanges, and sits in Layer 3 of the build-out stack. Constituent of Rubin Build-Out 100.
