Western Digital (WDC +10.70%) stock was a winner by association on Wednesday, thanks to the latest performance of its long-standing rival. After market hours, its fellow computer storage specialist, Seagate Technology, delivered quarterly results that far exceeded expectations. In its earnings release, Seagate highlighted the highly positive impact of artificial intelligence (AI) on its business. Like Seagate, Western Digital is a high-profile, veteran purveyor of such products. However, we should hold off until Thursday -- Western Digital is scheduled to release its own fiscal second quarter numbers then, and we'll get a clearer picture of how well it's doing in the midst of the AI gold rush.
