Western Digital, a prominent player in the hard disk drive and data storage market, has recently emerged as a standout performer on the S&P 500, with an impressive year-to-date gain of over 150% and a remarkable 80% increase in the past quarter. The company’s stock price reached an intraday record following analysts’ upward revisions of their price targets, reflecting robust confidence in its future prospects.
In a recent discussion, Kevin Cassidy, managing director and senior research analyst at Rosenblatt Securities, shed light on the factors contributing to this bullish outlook. He pointed to two major trends driving Western Digital’s performance: the proliferation of artificial intelligence (AI) data centers and the pressing need for high-capacity storage solutions.
As AI technology continues to evolve, many data centers are being proposed and developed in anticipation of enhanced capabilities over the next two to four years. Cassidy emphasized that every data center requires significant storage infrastructure, a domain where Western Digital excels by providing hard disk drives renowned for offering the most economical mass data storage solutions available. He noted that the more data these centers can process and store, the better the outcomes generated by AI applications.
To elucidate the role of hard disk drives, Cassidy provided an example with Yahoo Finance. The data generated from videos hosted on the platform, for instance, is stored on hard drives, which then can be utilized to run AI algorithms. This, in turn, can lead to insights about viewership trends or content optimization.
When asked about the broader implications of the AI demand on the hard drive industry, Cassidy confirmed that both Western Digital and its competitor Seagate, which also manufactures hard disk drives, are benefiting from this upsurge. Traditionally, most personal computers were equipped with hard disk drives; however, the rise of solid-state drives (SSDs) has shifted this landscape. Today, approximately 90% of PCs utilize SSDs due to their energy efficiency and compact data storage capabilities, which had previously presented a challenge for hard drive manufacturers.
Cassidy highlighted that this shift in the market dynamics has now removed a significant headwind for both companies. Instead of facing declining revenue streams from personal computer sales, they are witnessing an annual revenue growth rate of about 15% from cloud data centers over the next five years. This newfound growth trajectory, combined with improved profitability, has resulted in a higher market valuation for both Western Digital and Seagate, as investors recognize the long-term potential within the rapidly expanding data storage sector.
