Western Digital stock price slips into March as insider filing and AI jitters loom

NEW YORK, March 1, 2026, 12:56 EST — Market closed.

  • Western Digital shares ended Friday down 0.9% at $279.70
  • An SEC filing showed a small sale by the company’s chief legal officer under a 10b5-1 plan
  • Investors now look to a busy week for tech sentiment, led by U.S. jobs data and a Western Digital conference slot

Western Digital Corp shares closed down 0.9% on Friday at $279.70, capping a choppy finish to February as investors cut exposure to growth names ahead of Monday’s reopen. 1

The pullback matters because Western Digital sits in the slipstream of the AI buildout trade — and that trade just got a lot more nervous. U.S. stocks posted their steepest monthly drops in about a year as worries about AI disruption mixed with tariff and geopolitical uncertainty, and investors rotated toward defensive sectors. “There are still some cracks out there,” said Ryan Detrick, chief market strategist at Carson Group. 2

Western Digital had already slipped 3% on Thursday, lagging a mixed market session, while peer Seagate also fell and trading volume in Western Digital ran above its recent average, MarketWatch data showed. 3

A separate focus late in the week was insider activity. A filing showed Chief Legal Officer and Corporate Secretary Cynthia L. Tregillis sold 214 shares on Feb. 26 at $286.11 and had 770 shares withheld at $290.95 to cover tax obligations tied to vesting equity, leaving her with 133,781 shares. The filing said the sale was made under a pre-arranged 10b5-1 trading plan adopted in May 2025. 4

The amounts are small, and the tax-withholding line is routine, but filings like this can draw extra attention when a stock is already swinging with broader tape. A 10b5-1 plan is a preset trading program executives use to schedule trades in advance.

For the week ahead, macro headlines could do more work than company-specific news. The February U.S. jobs report is due March 6 and is expected to show job growth of 60,000, according to a Reuters poll. “The U.S. equity market is sort of in its late cycle,” said John Velis, Americas macro strategist at BNY, as investors try to “find the winners and losers” of disruptive tech. 5

On the company calendar, Western Digital is slated to present at the Morgan Stanley Technology, Media & Telecom Conference on Tuesday, March 3, according to the company’s investor-event listing. 6

That appearance is likely to be scanned for any read-through on enterprise storage demand and pricing, particularly for large data-center customers that can shift orders quickly when budgets tighten.

But the setup cuts both ways. If “risk-off” trading deepens — investors favoring safer sectors over cyclical growth — Western Digital and other storage names could keep tracking the mood around tech spending, rate expectations and any fresh AI-related scares.

With markets reopening Monday, traders will watch whether Western Digital stabilizes after late-week weakness, with the March 3 conference slot and the March 6 jobs report as the next clear catalysts.
