Sandisk, Micron Lead Chip Stocks Rally on Analyst Calls and Micron U.S. Spending Boost

Sandisk and Micron lead the move

Sandisk and Micron led a rally in chip stocks on July 9, with memory-chip names drawing strong bids after fresh analyst support for Sandisk and a larger U.S. investment plan from Micron.

Sandisk rose more than 9% as investors reacted to higher price targets from two Wall Street firms. Wedbush Securities analyst Matt Bryson reiterated an outperform rating and lifted his 12-month target to $2,000 from $1,200.

Bernstein analyst Mark Newman also kept an outperform rating on Sandisk and set a $3,000 price target. Newman said Sandisk and Micron could benefit from longer-term supply agreements tied to AI data-center demand.

Micron expands its U.S. push

Micron was the other major driver of the sector move. The company said it is accelerating U.S. fab and technology investments and increasing expected spending to more than $250 billion through 2035, up from $200 billion.

Micron said it still aims to produce 40% of its DRAM chips in the U.S. The company also said it plans to invest up to $3 billion to strengthen the U.S. semiconductor supply-chain ecosystem.

That broader plan includes $500 million in strategic financing for GlobalWafers, which is building a 300mm silicon wafer facility in Sherman, Texas. Micron and GlobalWafers also entered a 10-year supply agreement for advanced wafer capacity.

Why investors cared

The market treated Micron’s announcement as more than a capital-spending headline. It connected a major memory supplier to the domestic manufacturing and supply-chain buildout investors have been favoring in AI infrastructure names.

Memory chips remain a volatile part of the semiconductor market, but traders continue to look for signs that AI data-center demand can support pricing, volume, and longer contract visibility. That is the common thread linking the Sandisk analyst calls and Micron’s announcement.

The Philadelphia Semiconductor Index rose about 4.5% during the session, showing that the move was not limited to a single stock. Micron shares rose more than 7% to about $1,016.94 in afternoon trading.

What remains to be seen

Two questions remain open. First, how much of Micron’s newly announced U.S. spending is incremental versus already planned capital. Second, how quickly the company can convert the investment plan into actual capacity.

Traders are also watching whether Sandisk can hold its gains once the analyst upgrades fade and whether the rally broadens beyond memory names. For now, the day’s move reflected renewed confidence that AI data-center demand and domestic manufacturing remain powerful sector catalysts.
