Western Digital WDC

Investment case

HDD and nearline storage — the cold-data tier of the AI data center.

Scarcity / moat

One of the two global HDD duopolists.

Competition

Seagate (STX) as the other duopolist, and the long-run substitution of SSD for HDD.

Risk

The least elastic name on this list; a defensive position rather than a thesis expression.
