Western Digital rises after Morgan Stanley boosts price target by 33%, while Seagate climbs on AI storage optimism

Western Digital’s stock surged Tuesday, rising about 7% in morning trading and changing hands near $701, according to market coverage. The move pushed the shares to a fresh all-time high, underscoring how quickly sentiment can shift in the memory and storage supply chain when brokerage views change.

The immediate catalyst cited in the report was a research note from Morgan Stanley. The note reiterated an Overweight rating on Western Digital and raised its price target by 33%. For investors, a larger price target often indicates a more optimistic outlook for a company’s earnings power, even when the underlying business and near-term guidance have not changed.

Alongside Western Digital’s jump, Seagate shares were reported to be up about 5%. The pairing of the two storage names reflects a broader market theme, namely expectations that artificial intelligence spending will keep driving demand for data storage and related hardware infrastructure.

Morgan Stanley’s upgraded stance matters in part because storage has been trading like a cyclical technology segment, where earnings expectations can swing with memory pricing and with how quickly cloud operators and AI builders translate capacity buildouts into purchases. While the report did not describe any specific operational update from Western Digital, brokerage price-target changes can still move stocks quickly when the market is waiting for clearer demand indicates.

In practical terms, Western Digital and Seagate are both positioned in the systems that store and move large volumes of data. When investors believe AI deployment will increase the amount of compute and the amount of data those systems must manage, storage providers often benefit from the expectation of higher volumes, improved pricing, or both.

Still, the report provided limited detail on what specifically drove the 33% increase in the price target, beyond the fact that Morgan Stanley lifted it while maintaining its Overweight rating. It also did not cite any new company filing, earnings update, or changes to product shipments that would independently explain the move.

What is clear from the coverage is the market reaction itself. Western Digital’s advance and the stock’s movement toward a new peak suggest buyers were willing to pay up on The announcement that at least one major Wall Street firm saw more upside than previously expected.

Looking ahead, traders will likely watch for follow-through from other brokerages, any additional commentary from firms covering memory and storage, and company-level updates that could confirm whether AI-driven demand is translating into sustained revenue strength. Without more granular disclosure in the coverage, the durability of the rally will depend on whether subsequent data points validate the higher expectations reflected in the new price target.
