Key PointsSandisk shares are climbing approximately 6% Tuesday following Monday’s 13% decline amid widespread semiconductor sector weaknessKeyBanc released an optimistic report on competitor Micron, highlighting robust AI data center demand across AsiaOngoing supply constraints in NAND and DRAM markets continue driving memory pricing upwardSandisk anticipates delivering initial high-bandwidth flash (HBF) memory samples this year, targeting commercial rollout by 2027Analyst sentiment remains divided — Wall Street consensus leans Buy, while SA analysts average Hold, citing elevated valuation concerns at approximately 57x trailing earningsSandisk investors have endured a turbulent period recently. Shares tumbled 20% across a two-week span, highlighted by Monday’s brutal nearly-13% decline during a sector-wide chip stock rout. However, Tuesday is offering some respite — SNDK is currently trading up roughly 6% at mid-morning.Sandisk Corporation, SNDKWhat’s driving the recovery? A research note from KeyBanc focused on Micron.KeyBanc conducted site visits at AI data center facilities throughout Asia and returned with compelling findings: appetite for AI processors and high-bandwidth memory remains robust. Persistent supply limitations in both DRAM and NAND continue elevating prices, prompting KeyBanc to increase its Micron price target.While Sandisk didn’t receive its own price target increase from KeyBanc, the implications are clear. Micron produces both DRAM and NAND memory, whereas Sandisk focuses exclusively on NAND. Nevertheless, KeyBanc explicitly highlighted supply deficits in both categories — sufficient to boost Sandisk alongside its competitor.Industry observers anticipate the memory market will remain constrained for an additional two to three years. SA analyst Hunting Alphas identified memory capacity as “the key bottleneck in scaling AI inferencing workloads.”Sandisk is developing a potential solution to this constraint. The company is advancing high-bandwidth flash (HBF) memory technology, with initial samples anticipated later this year and full commercial availability targeted for 2027. Hunting Alphas forecasts this innovation could generate “massive revenue growth” throughout the next two fiscal years.Diverging Analyst PerspectivesNot all analysts share this optimism. SA analyst David Desjardins noted that Sandisk has secured just five supply agreements to date — accounting for approximately one-third of its projected bit production for fiscal 2027. He additionally cautioned that the cyclical characteristics of the NAND industry could deteriorate rapidly when fresh supply enters the market in early 2026.“Paying ~7.5x peak earnings is actually expensive,” Desjardins observed.Wall Street consensus maintains an average Buy rating. Citi reaffirmed a $2,500 price objective, while Evercore ISI delivered a striking upgrade — elevating its target to $3,100 from $1,400.Valuation Remains Central DebateSandisk currently trades at more than 57x trailing earnings. That represents a substantial premium, even for shares that have surged 605% year-to-date and 3,840% over the trailing twelve months.The bullish argument is clear-cut: if NAND pricing continues ascending and profitability expands accordingly, that P/E multiple contracts rapidly. The bearish counterargument is equally straightforward: any indication that supply is normalizing or customers are optimizing memory utilization could trigger sharp declines.SA Quant assigns SNDK a Strong Buy rating. SA analysts on average recommend Hold. Wall Street consensus favors Buy.Evercore ISI’s $3,100 price objective represents the most optimistic forecast currently on Wall Street.The post Sandisk (SNDK) Stock Rebounds 6% Following 13% Monday Collapse — Here’s Why appeared first on Blockonomi.
