Sandisk Leads Nasdaq to Record High on AI Storage Demand

The Nasdaq Composite reached a new record high of 27,272.72 on Tuesday, driven primarily by a sharp rally in Sandisk rather than a broad-based semiconductor surge. The index closed at 27,192.82, up 0.26%, as lower crude oil prices and falling Treasury yields created a favorable environment for growth assets.

Sandisk shares climbed 6.52% to $1,881.81 after Rosenblatt initiated coverage with a buy rating and a $2,400 price target. This move highlighted a shift in the AI trade, where investors are prioritizing specific storage components over general chipmakers like Nvidia, which remained flat during the session.

Sandisk drives AI storage narrative

Rosenblatt analyst Kevin Cassidy argues that artificial intelligence has fundamentally altered the NAND flash market, moving it away from commodity pricing toward premium system component status. He projects Sandisk’s data-center revenue will reach $21.7 billion in fiscal 2027 and $28.6 billion in fiscal 2028, driven by multiyear supply agreements with eight major customers at fixed prices.

The firm’s vertical stacking technology, developed with Kioxia, allows for higher density and faster data handling required by large language models and inference workloads. This structural change in demand supports the stock’s recovery from its August low of $998.19, with the current price well above the 50-day moving average of $1,505.37.

Macroeconomic factors support tech rally

Geopolitical developments provided additional tailwinds for the market, as reports that Iran could reopen the Strait of Hormuz within seven days sent oil prices lower for a fifth consecutive session. Brent crude slipped toward $100, reducing inflationary pressure and allowing the 10-year Treasury yield to ease near 4.90% from a recent peak of 5.041%.

According to FXEmpire, these macro conditions gave the Nasdaq room to break through its previous all-time high of 27,190.21. The index has reclaimed its 50-day moving average at 26,114.78 and cleared several swing tops, indicating that the primary trend remains upward despite the narrow breadth of the rally.

Rotation within large-cap tech

The rally was not uniform across the sector, as Alphabet opened strong at $364.17 but faded to close down 0.94% at $351.63. While AMD crossed a $1 trillion valuation earlier in the week, Tuesday's gains were concentrated in names with fresh catalysts, such as Sandisk and Vicor, which raised its third-quarter revenue outlook.

Investors are selectively allocating capital toward parts of the AI buildout with clear demand drivers, rather than buying the entire technology sector. This rotation suggests that while the index sets records, the underlying performance relies on specific supply chain components benefiting from infrastructure expansion.
