Western Digital produces DRAM-based hard disk drives (HDDs) along with non-volatile memory (NVM) products, including solid data drives (SSDs) and mobile memory. WDC's products are used in cloud and on-premises data centers, desktop & notebook PCs, enterprise storage, video surveillance, networking products, DVRs, point-of-sale devices, and set-top boxes. In May 2016, WDC acquired NAND flash leader SanDisk. In October 2023, WDC announced plans to unwind that acquisition and spin off the NAND flash business.

Insider-sentiment data from Vickers Stock Research reflects nice relative improvement this week, with the caveat that transaction volume is cyclically low as corporate insiders are currently broadly prohibited from trading due to earnings season. Even so, the one-week sell/buy ratios from Vickers are all in the lower (positive) zone of the neutral range after having spent the past few weeks in the middle to upper range of that same neutral zone. That has led to either slight improvement or at least a plateauing in the eight-week sell/buy readings, all of which are squarely in the middle of the neutral range. And with all the issues in play right now (the U.S. election, the Middle East, the Fed's next move, the behavior of Treasury yields, the ultimate quality of the current earnings season, etc.), neutral seems to be a reasonable posture to take at the moment. On a sector basis, insider selling outpaced buying in the Consumer Discretionary sector, with shares valued at roughly $63 million sold versus less than $5 million bought. Selling by insiders was also evident in the Financial sector, with shares valued at $42 million sold versus less than $3 million bought, as well as in the Industrial sector, with $33 million sold versus $1 million bought. This week, analysts at Vickers highlighted insider transactions of interest at PBF Energy Inc. (NYSE: PBF) and Philip Morris International Inc. (NYSE: PM).

Western Digital is a leading vertically integrated supplier of data storage solutions, spanning both hard disk drives and solid-state drives. In the HDD market it forms a practical duopoly with Seagate, and it is the largest global producer of NAND flash chips for SSDs in a joint venture with competitor Kioxia.
