“FTAI Aviation Ltd., Astera Labs, Inc., and Western Digital Corporation were among the top detractors from performance.”
Western Digital Corporation - September 2026
“Western Digital Western Digital detracted from performance in the third quarter despite strong fiscal fourth quarter results and a guide for continued revenue and margin expansion.”
Western Digital Corporation - September 2026
“Western Digital Corporation, 2.72%;”
Western Digital Corporation - September 2026
“• Western Digital is a leading provider of hard disk drives, which store vast quantities of data for cloud providers, enterprises, and data centers. Following the separation of its flash-memory business, the company now focuses primarily on high-capacity hard drive storage. We believe Western Digital is well positioned to benefit from the continued expansion of data, as artificial intelligence applications generate enormous volumes of information that must be stored reliably and at low cost. Shares detracted from performance during the quarter despite strong operating results and sustained demand from cloud customers.”
Western Digital Corporation - HoldsAlger Spectra FundSeptember 2026
“Western Digital Corporation, Nebius Group, and Space Exploration Technologies Corp. were among the top detractors from performance.”
Western Digital Corporation - June 2026
“• Western Digital is a hard disk drive (HDD) storage company benefiting from rising hyperscaler data-center investment and the continued proliferation of data. The HDD industry is highly consolidated, with only two scaled manufacturers, and Western Digital holds a leading market position. The business has structurally shifted toward cloud customers as consumer exposure has declined, with cloud representing the majority of Western Digital’s revenue. Importantly, industry participants have emphasized capital discipline—prioritizing higher areal density (i.e., more terabytes per drive) rather than adding significant unit capacity—which supports a healthier supply/demand balance and improved profitability. Shares contributed positively to performance after the company delivered strong fiscal third- quarter results.”
Western Digital Corporation - June 2026
“On the one hand you have got businesses that touch AI, whose stocks keep going up daily to what we believe to be unsustainable levels. We are not complaining. We were early on Western Digital Corp (WDC) and we still own Silicon Motion (SIMO).”
Western Digital Corporation - June 2026
“NVIDIA, Micron, Broadcom, AMD, Applied Materials, Seagate, Western Digital, Corning, SiTime, TSMC, ASML, and Sandisk were among the positions that contributed to the quarter’s technology-led gains.”
Western Digital Corporation - New positionAristotle Atlantic Focus Growth StrategyJune 2026
“Western Digital We initiated Western Digital because we view the company as providing picks-and-shovels exposure to the AI memory bottleneck, with hard disk drives and NAND flash memory now serving as capacity-constrained inputs to AI data center buildout.”

Western Digital Corporation - June 2026
“Top Contributors Advanced Micro Devices (AMD), a leading semiconductor manufacturer, outperformed on strong AI data center demand, which drove record sales across its CPU and GPU portfolios. Applied Materials, which supplies semiconductor manufacturing equipment, continues to see higher demand from foundry customers tied to AI infrastructure build-out, as hyperscalers boosted spending to support accelerating compute needs. Western Digital, a leading data storage products maker, outperformed after the company's strong quarterly results, which reiterated powerful, multiyear support from AI data center storage demands.”
Western Digital Corporation - June 2026
“YTD Attribution4 1. Our underweight position in Information Technology was the primary detractor to performance in the quarter as it has been the best performing sector within the Russell Midcap® Value benchmark, up more than 80 percent year to date. In particular, the Technology Hardware, Storage & Peripherals industry was up more than 260 percent through the end of the second quarter of 2026, led by strong price appreciation in Sandisk Corporation (SNDK), Western Digital Corporation (WDC), and Hewlett Packard Enterprise Co. (HPE), none of which we owned.”

- September 2026
“Over the last few years, we have observed a number of stocks on multiple occasions with meaningful weight in the Russell Midcap® Value Index that bear little resemblance to the classic value businesses we have bought and sold over time. Recent examples include Robinhood Markets, Inc. (HOOD), Strategy Inc (MSTR) (formerly MicroStrategy Inc.), Coinbase Global, Inc. (COIN), Western Digital Corporation (WDC), and Sandisk Corporation (SNDK), among others.”
Western Digital Corporation - September 2026
“1. Our underweight position in Information Technology was the primary detractor to performance as it was the best-performing sector this in the first half of the year within the Russell 3000® Value benchmark, up almost 90 percent year to date. In particular, the Technology Hardware, Storage & Peripherals industry was up more than 315 percent through the end of the third quarter and the Semiconductors & Semiconductor Equipment industry was up almost 140 percent. This has been led by strong price appreciation in Sandisk Corporation (SNDK), Western Digital Corporation (WDC), Micron Technology, Inc. (MU), and Intel Corporation (INTC), none of which we owned.”
Western Digital Corporation - MentionedAristotle Value Equity StrategySeptember 2026
“Concentrated capital, driven by speculative enthusiasm and drawing attention away from fundamentally stable, predictable businesses; we’ve spoken about this at length. More recently, significant changes in the composition of our primary benchmark, the Russell 1000 Value, have reshaped the Index. Seven of the Index’s ten largest contributors to returns during the first half of the year were removed at the end of June: Micron, Caterpillar, Applied Materials, AMD, Sandisk, Western Digital and Marvell Technology.”
Western Digital Corporation - MentionedAurora Investment Counsel Investment ManagementSeptember 2026
“In today’s market, stocks like Corning, Micron Technology, and Western Digital (all stocks that blew both up and down in the early 2000’s) are up 200-300% and more in the last 12 months. These valuations can move just as quickly in reverse if there is a drop off in demand.”
Western Digital Corporation - June 2026
“The Russell Midcap Index gained +13.8% in the second quarter of 2026, and the Russell Midcap Value Index returned +13.4%. Equity markets posted strong returns despite accelerating inflation, an increasingly hawkish Federal Reserve, and an oil shock stemming from the conflict in Iran. Market leadership was exceptionally narrow. Many semiconductor stocks, and other parts of the AI complex—particularly hardware and storage—recorded returns in excess of 100%. In the Russell Midcap Value, the hardware and storage group alone carried an average weight of roughly 10% and returned +84% for the quarter, with names such as SanDisk and Western Digital more than doubling.”
Western Digital Corporation - MentionedMD SASS Concentrated ValueJune 2026
“Because many of those suppliers, including Micron, Intel, Western Digital, Dell, and Marvell, were traditionally viewed as cyclical businesses,”
Western Digital Corporation - MentionedOakmark FundJune 2026
Named in a table in Oakmark Fund’s letter.
Western Digital Corporation - MentionedDiamond Hill Large Cap FundJune 2026
“Similar to recent quarters, the Fund’s technology exposure— companies we do not own, and to a lesser extent, companies we do own—continued to be the most notable detractor from relative performance. However, the magnitude was even greater with the sector driving nearly all the Fund’s underperformance in 2Q26. Not having exposure to a wide range of technology companies benefiting from AI-related capital expenditures, such as Micron, Sandisk, Western Digital and many others, was a very meaningful headwind to relative performance.”
