NEW YORK, Feb 24, 2026, 14:35 ET — Regular session
- Western Digital slipped roughly 2.8%, landing at $272.65. The stock had wrapped up Monday at $280.42.
- A senior executive signaled plans to unload restricted shares in a Form 144 filing posted late Monday.
- Management remarks at the Morgan Stanley conference on March 3 have caught investors’ attention.
Western Digital Corp slipped roughly 2.8% to $272.65 by Tuesday afternoon, fading from last week’s high amid a new insider-sale disclosure and a volatile session for tech stocks. Shares moved in a $267.85-to-$284.00 band. 1
This is notable: Western Digital, now packed with investors betting on AI-fueled data-center expansion, has seen its shares surge. That rally leaves the stock exposed—any whiff of softer demand or fresh supply-chain hiccups can spark a quick pullback. Even a minor filing sometimes nudges fast money to take some risk off the table.
Wall Street shook off some of the previous session’s losses, regaining ground after a punishing drop linked to tariff jitters and renewed fear that emerging AI products could quickly eat into software sector profits. “Yesterday’s reaction was so overdone that it can’t help but bounce a little bit,” said Ken Polcari, partner and chief market strategist at Slatestone Wealth. 2
On Monday evening, a Form 144 filing revealed Morgan Stanley Smith Barney planned to unload 130 restricted Western Digital shares on behalf of Cynthia Lock Tregillis, the company’s chief legal officer. The filing also tracked previous sales from the past three months. Form 144, tied to SEC Rule 144, deals with resales of restricted securities. 3
Western Digital shares slipped 1.8% to finish Monday at $280.42, trailing behind some in the sector as risk assets sold off. Seagate Technology gave up 0.9%, NetApp saw a 1.9% drop, and trading in Western Digital stayed lighter than its 50-day average, according to MarketWatch data. 4
The filing was minor. But it hit just as traders are weighing if the storage cycle has topped out, after a rush of orders linked to AI servers and cloud buildouts. In this market, “not much” sometimes tips the scale.
Bulls face two headaches: tariff policy and choppy tech sentiment could keep draining capital from high-beta hardware names, regardless of steady demand. Throw in more insider moves or a tweak in how customers allocate budgets, and suddenly the durability of today’s pricing setup looks a lot less certain.
The company pointed to management’s scheduled appearance at Morgan Stanley’s Technology, Media & Telecom Conference on March 3 as the next chance for investors to get more details on supply and demand. 5
