SanDisk Surges 7% as Memory Stocks Rebound From Kioxia Selloff; Micron and Western Digital Rise 4%

SanDisk (SNDK) surged 7% after a 35% monthly decline, rebounding from a Kioxia selloff. Kioxia's flat profit guidance and slowing NAND price gains impacted memory stocks. SanDisk's peers, Micron (MU) and Western Digital (WDC), also rose 4%. SanDisk's direct NAND exposure and long-term contracts may support demand. Analysts' views are mixed, with targets ranging from $1,300 to $2,000. Apple's (AAPL) comments on rising memory costs provide a positive signal.

Prediction: This Will Be Sandisk’s Stock Price After 1 Year

Sandisk (SNDK) reported fiscal Q1 2027 revenue of $11.03B, up 378% YoY, and EPS of $49.51, exceeding expectations. The company guided for Q2 revenue of $12.4B and EPS of $56.00, both above analyst estimates. Despite a 13% stock drop post-earnings, analysts expect 88% gains over the next year, with potential for further upside due to strong growth and low valuation.
