On July 20, Western Digital rose 3.1% in pre-market trading, trading at approximately $492.01 per share, with turnover of $9.69 million. The broader storage sector strengthened in tandem, with SanDisk up 4.62% and Seagate Technology up 3.13%.

On the news front, the rally is primarily driven by sustained artificial intelligence infrastructure buildout, with accelerating demand for high-capacity enterprise HDDs and SSDs. Additionally, optimistic expectations surrounding the company's strategic split of its flash memory and hard drive business units continue to support market sentiment. Selling pressure triggered earlier by the Korean Financial Services Commission's decision to raise minimum margin requirements for single-stock leveraged ETFs has been largely digested. Meanwhile, multiple investment banks recently raised their target prices on the stock — Citi to $800, BNP Paribas to $660, and UBS to $560 — signaling notable capital inflows back into the sector.
