SanDisk’s Independence Week: A 22% Surge, a Record High, and a Sudden 6% Retreat

SanDisk’s long-awaited split from Western Digital has unleashed a trading frenzy that saw the stock swing violently in both directions within days. The memory-chip specialist hit an all-time high of $2,354 on Monday—the same day Western Digital offloaded its final stake of roughly one million shares in private transactions. But the real fireworks came on Thursday, when the stock surged as much as 22% in a single session, before closing the week with a 6% drop on Friday to $2,192.

The departure of Western Digital removes a persistent overhang of shares from the market, but it also amplifies the volatility inherent in a company that now stands on its own. Retail investors have piled into the name, propelling trading volumes to extreme levels and making SanDisk a trending topic on social media platforms. The 30-day annualized volatility has hit 117%, a stark reminder that this is no ordinary equity market.

The company’s year-to-date gain—calculated at roughly 697%—has been fueled by a stunning recovery from an October 2025 low of $146, a move that represents a gain of over 1,400% for those who bought the dip. That kind of performance has attracted institutional interest as well: Trust Asset Management added 1,551 shares in the first quarter, and Falcon Wealth Planning invested around $386,000.

Apple’s Price Shock and the NAND Squeeze

Underpinning the rally is a brutal supply-demand imbalance in the memory market. On June 25, Apple raised prices on Mac and iPad models by 15% to 25%, citing catastrophic conditions in the memory supply chain. Memory components now account for 35% of a laptop’s material costs, up from the historical range of 15% to 18%. The culprit is the insatiable appetite of AI data centers, which are expected to consume 70% of global memory production in 2026. NAND and DRAM prices have surged 400% since the fourth quarter of 2025, and industry experts see supply constraints persisting until at least 2027.

Should investors sell immediately? Or is it worth buying SANDISK?

SanDisk is a direct beneficiary of this trend. The company’s revenue reached nearly $6 billion in the latest quarter, with a gross margin of 56% and operating profit of $4.11 billion. Analysts forecast full-year earnings of around $64 per share. On the pricing side, Citigroup raised its price target on June 26 from $2,025 to $2,500, maintaining a buy rating. The bank highlighted multi-year take-or-pay contracts with customers and a 233% quarter-over-quarter jump in data-center revenue as key catalysts.

The Flip Side of a Boom

Yet the risks are as extreme as the rewards. SanDisk trades at a price-to-earnings multiple between 65 and 76—levels that leave little room for disappointment. If AI-related capital spending ever slows, the correction could be severe. The boom-bust pattern that memory cycles are known for is fully on display, and any shift in hyperscaler budgets from Microsoft, Meta, or others would hit SanDisk hard.

For now, the company is riding the most intense memory boom in decades. Management will provide further details on its 3D-NAND architecture strategy at an investor day in August. Until then, the stock remains a high-stakes play on whether AI’s demand for storage will continue to outrun supply—and how much volatility investors can stomach along the way.
