Sandisk Corporation (NASDAQ: SNDK) surged 14.5% in a single trading session, closing at a record high after briefly touching $1,895 during intraday trading. The rally marked a significant milestone for the memory and storage giant as investor enthusiasm around artificial intelligence infrastructure continued to accelerate across semiconductor markets.

Shares opened at $1,672.26 before climbing steadily throughout the session, ultimately finishing at $1,881.51. Trading activity was also elevated, with volume reaching more than 13 million shares, reflecting strong institutional participation in the move.

The surge came amid a broader rebound in chip stocks, with investors aggressively rotating back into AI-linked hardware names following recent volatility in the sector.

Semiconductor Sector Rebounds Strongly

The rally was not isolated to Sandisk. Semiconductor equities experienced a broad-based surge, with the PHLX Semiconductor Index rising 7.9% in its strongest single-day performance since April 2025. Major memory and storage peers also posted solid gains, reinforcing the strength of the sector-wide rebound.

Industry peers such as Micron Technology and Western Digital also advanced sharply, signaling renewed optimism around memory pricing cycles and AI-driven demand for high-performance storage solutions.

Market participants pointed to a clear shift in sentiment as investors re-entered semiconductor names tied directly to data-center expansion, AI model training, and cloud infrastructure scaling.

Earnings Strength and Growth Outlook

Sandisk’s rally has been underpinned by its recent financial performance and forward guidance. In its latest fiscal third-quarter results, the company reported $5.95 billion in revenue, representing a massive year-over-year increase driven primarily by data-center demand and AI-related storage deployments.

Net income climbed to $3.615 billion, while non-GAAP diluted earnings per share reached $23.41. Particularly notable was the company’s data-center segment, which surged 233% quarter-over-quarter to $1.467 billion, highlighting the rapid acceleration of enterprise storage demand.

Management described the period as a “fundamental inflection point,” emphasizing long-term customer agreements and expanded participation in higher-value enterprise markets. The company also reported multiple signed New Business Model deals, reinforcing visibility into future revenue streams.

Wall Street Turns Increasingly Bullish

Investor sentiment has grown increasingly positive following the earnings release. Several analysts have raised price targets, with one major bank increasing its outlook to $2,100 from $1,550, citing stronger-than-expected memory pricing and contracted supply agreements that reduce revenue volatility.

The broader analyst landscape remains supportive, with the majority of coverage rating the stock as a Buy. However, estimates remain widely dispersed, reflecting differing expectations about the durability of the AI-driven memory cycle.

The average 12-month price target currently sits slightly below recent trading levels, suggesting that while optimism is strong, markets are still pricing in execution risk and sector cyclicality.

Outlook Hinges on AI Cycle Durability

Looking ahead, Sandisk faces a critical test as it works to meet ambitious forward guidance. The company is projecting fiscal fourth-quarter revenue between $7.75 billion and $8.25 billion, alongside strong non-GAAP margin expectations in the 79% to 81% range.

Earnings per share guidance of $30 to $33 further underscores management’s confidence in sustained demand conditions. However, investors remain focused on NAND pricing trends, supply discipline across the industry, and whether long-term AI infrastructure contracts can smooth out traditional memory market volatility.
