Seagate, Western Digital and Sandisk in focus as storage shares come under pressure

· 6 sources

Storage stocks Seagate, Western Digital and Sandisk draw coverage as shares of several hardware names fall, with attention on results, margins and AI demand.

What happened

Shares of several hardware and chip-related companies fell, including Seagate, Western Digital, Vishay Intertechnology, Impinj and Allegro MicroSystems, according to The Globe and Mail.

Ad-hoc-news.de reports that Seagate is in focus after record fiscal results and a higher outlook for its second quarter, and describes the stock as facing an execution test. The same outlet also says Western Digital stock dropped as its margin outlook met trading pressure.

Barchart.com published a piece asking whether Wall Street is bullish or bearish on Western Digital. Kalkine says AI storage demand and long-term contracts support growth and earnings visibility at Sandisk.

Context

Seagate and Western Digital are well-known makers of data storage products, and Sandisk is also active in the storage market. Demand for storage is often linked to data-center and AI spending.

Why it matters

The coverage shows how results, margin expectations and AI-related demand are shaping attention on storage companies, though the sources do not establish a single cause for the declines.
