What Happened?
Shares of data storage manufacturer Seagate (NASDAQ: STX) jumped 6.8% in the afternoon session after positive sentiment spilled over from competitor Micron Technology's strong earnings report, which highlighted a surge in demand for data storage driven by artificial intelligence.
The move came as the data storage sector experienced a significant rally following Micron's monumental results. This report pointed to a "Storage Supercycle," signaling that the industry was struggling to keep up with the intense demand from AI applications. While the sector saw a brief, early pullback as some investors took profits, the underlying positive trend appeared to resume. Micron's strong performance reinforced the view of a structural bull market for storage, driven by persistent supply constraints and the massive need for memory in the AI value chain.
The shares closed the day at $434.60, up 6.8% from previous close.
