SanDisk shares have risen about 4,000% [1] over the past year, prompting Barclays to upgrade the stock and raise its price target.
The surge reflects a volatile but aggressive expansion in the memory chip sector. As demand for NAND flash storage outstrips available supply, investors are pivoting toward memory makers to capitalize on significant earnings growth.
Barclays upgraded the stock to Overweight and increased the price target to $2,300 [1]. This is a substantial increase from the previous target of $1,200 [1]. The upgrade comes as the company continues to navigate a high-growth environment in the U.S. stock markets.
Other metrics highlight the stock's rapid ascent this year. SanDisk has seen a year-to-date gain of more than 550% [3]. In a single trading session, the stock experienced an 11% rise [4].
Market analysts said the growth is due to a combination of strong demand and a supply shortage of NAND flash storage [5, 6]. This imbalance has created a favorable environment for companies capable of scaling production to meet the needs of data centers, and consumer electronics.
While the 4,000% rise over the 12-month period ending May 2026 [1] has drawn attention for its speed, the Barclays upgrade suggests that the firm believes there is further room for growth. The shift to an Overweight rating indicates a belief that the stock will outperform the broader market in the near term.

The dramatic rise in SanDisk's valuation underscores a critical bottleneck in the global semiconductor supply chain. When essential components like NAND flash storage face shortages, the resulting pricing power can lead to exponential stock growth. However, the sheer scale of a 4,000% annual increase often triggers scrutiny regarding whether the market has overextended or if the fundamental shift in storage demand is permanent.
