Is Western Digital Stock Underperforming the Nasdaq?

Western Digital Corporation (WDC) is a data storage technology company that develops, manufactures, and sells hard disk drive (HDD)-based storage products and solutions. Its portfolio spans internal and data-center drives, external and portable storage, network-attached storage (NAS) devices, and related accessories.

The San Jose, California-based firm also collaborates on quantum error-correction technology to advance reliable quantum computing. Such a substantial operating footprint has helped the firm reach a market cap of nearly $147.2 billion, placing it above the $10 billion threshold used to define large-cap stocks.

Despite that scale, Western Digital's recent stock performance has been considerably weaker. The shares are currently trading 48.5% below their 52-week high of $799.87, which was reached in June. Also, over the past three months, WDC stock has fallen roughly 37%, while the Nasdaq Composite ($NASX) declined only 2.6% during the period.

The picture changes dramatically when the time frame is extended. Over the past 52 weeks, WDC stock has surged 302.3%, compared with an approximately 16.3% gain for the index. The year-to-date (YTD) comparison is similarly striking, as WDC stock is up 139.1%, while the benchmark has gained roughly 11.8% in the same stretch.

From a technical perspective, Western Digital has maintained a position above its 200-day moving average of $381.88 since October 2025. The stock also traded mostly above its 50-day moving average from October 2025 onward, before slipping below it in July. Since then, WDC stock has remained below its 50-day moving average of $489.27.

The HDD maker's long-term rally reflects stronger demand for data storage, particularly from cloud infrastructure and artificial intelligence (AI) workloads. Its HDD business has benefited from rising demand for high-capacity drives, while the separation of its flash business allowed the company to focus on its core storage operations and improve capital allocation.
