Western Digital Is the Best-Performing Nasdaq-100 Stock. Can It Keep Going?

Western Digital (WDC) is up 59% year-to-date as the Nasdaq-100‘s top performer, driven by surging demand for its high-capacity hard disk drives used in AI data centers, with the company’s entire 2026 production capacity already sold out and multi-year contracts locked in through 2027-2028. Sandisk (SNDK), spun off from Western Digital’s flash-memory business, has also benefited from the broader storage rally but recently pulled back.
The AI data explosion is structural and ongoing, creating sustained demand for storage capacity that ensures Western Digital maintains pricing power and margin expansion for years as hyperscale cloud providers and data-center operators scramble to build out infrastructure for AI training and inference.
A recent study identified one single habit that doubled Americans’ retirement savings and moved retirement from dream, to reality. Read more here.
The stock market has been roiled lately, with a sharp sell-off hammering tech stocks in particular. Software and semiconductor names have taken the brunt of the pain, sending the Nasdaq-100 down more than 8% -- a steeper drop than the S&P 500’s roughly 7% decline.
It feels like a blanket statement at first glance: tech is getting crushed across the board. But that narrative misses the outliers. Some companies are proving remarkably resilient, shrugging off the broader gloom and delivering eye-popping gains. Western Digital (NASDAQ:WDC) stands out as one of them. The storage giant is up over 59% year-to-date, making it the top performer in the Nasdaq-100. Yet it has given back almost 14% from the all-time high it hit earlier this month.
The big question for investors is whether Western Digital can regain its momentum and keep powering higher.
Most Americans drastically underestimate how much they need to retire and overestimate how prepared they are. But data shows that people with one habit have more than double the savings of those who don’t.
The AI Storage Supercycle Is Just Getting Started
Western Digital’s surge isn’t a fluke -- it’s rooted in a structural shift that’s reshaping the data economy. After spinning off its flash-memory business into Sandisk (NASDAQ:SNDK), another high-flying stock that has taken a breather, the company has become a pure-play leader in high-capacity hard disk drives (HDDs), the workhorse storage solution for massive AI workloads.
Hyperscale cloud providers and data-center operators are scrambling for capacity to handle the exploding volume of training data, inference archives, and long-term “data lakes.” Western Digital's nearline HDDs deliver the perfect mix of scale, reliability, and low cost per terabyte that these customers crave. Demand has been so intense that the company’s entire 2026 production capacity is already sold out, with firm purchase orders locked in from its top clients extending into 2027 and even 2028. That visibility has translated into stronger pricing power and margin expansion.
Recent quarterly results underscored the momentum, with revenue jumping solidly year-over-year, earnings beating expectations, and management highlighting multi-year contracts that remove much of the cyclical uncertainty that once plagued the sector. Investors who spotted this AI-driven re-rating early have been rewarded handsomely.
Why the Stock Has Pulled Back From Its Highs
Even the strongest stories can hit temporary speed bumps. Western Digital touched an all-time high near $320 in mid-March before sliding roughly 14% amid the wider tech-sector sell-off. Part of it is classic “sell the news” dynamics -- investors locked in gains after a blistering run that saw the stock more than quintuple over the past year.
Broader market jitters around interest rates, geopolitical tensions, and profit-taking in the Magnificent Seven names added fuel to the retreat. Some light insider selling and digestion of the post-earnings rally also played a role. Importantly, none of this reflects any deterioration in the underlying business. Production remains fully booked, customer commitments are rock-solid, and the AI tailwind shows no signs of fading. The pullback looks more like a healthy breather than a fundamental reversal.
Wall Street Remains Bullish With Rising Price Targets
Analysts have taken notice of Western Digital's transformation and are increasingly upbeat. The consensus rating sits at Moderate Buy to Strong Buy, with the majority of the 24-plus firms covering the stock issuing Buy recommendations. Recent notes highlight the structural demand shift and the company’s disciplined execution.
Cantor Fitzgerald raised its target to $420, citing the multi-year visibility and margin upside. Mizuho moved to $340, Morgan Stanley to $369, and Wells Fargo lifted its call to the mid-$300s range after the latest investor presentations. While the street-wide average target sits around $265 to $330 per share, several high-conviction calls now stretch toward $440. The message is consistent: The AI storage supercycle creates a multi-year runway that justifies a premium valuation for a company that has already proven it can deliver.
Key Takeaway
Western Digital’s high-capacity HDDs are in white-hot demand, with supply already outstripped for 2026 and long-term contracts ensuring tight conditions well beyond. There is no let-up in sight -- the AI data explosion is structural, not cyclical. That dynamic points to sustained pricing power, robust revenue growth, and expanding margins for years to come.
For investors, the recent pullback from the all-time high isn’t a warning sign, but rather an attractive entry point into a stock that has already proven itself as the Nasdaq-100’s standout performer. Those who buy the dip today could be well-positioned to ride the next leg of the AI infrastructure boom higher.
Data Shows One Habit Doubles American’s Savings And Boosts Retirement
Most Americans drastically underestimate how much they need to retire and overestimate how prepared they are. But data shows that people with one habit have more than double the savings of those who don’t.
And no, it’s got nothing to do with increasing your income, savings, clipping coupons, or even cutting back on your lifestyle. It’s much more straightforward (and powerful) than any of that. Frankly, it’s shocking more people don’t adopt the habit given how easy it is.
