Here’s Why SanDisk Shares Rallied 14.5% on Thursday

SanDisk Corp (NASDAQ: SNDK) closed at $1,881.51 on Thursday, up $238.28 (+14.50%), after Oracle’s $70 billion capex guidance confirmed that hyperscaler demand for AI memory and storage is accelerating — not slowing.

Oracle reported fiscal Q4 earnings on Wednesday evening, revealing full-year capital expenditure guidance roughly $20–25 billion above consensus, driven by accelerated prepayments for data centre components. Oracle’s own stock fell more than 8.5% on margin concerns, but the read-through for memory and chip suppliers was unambiguously bullish — and SanDisk was a clear winner.

Shares opened at $1,672.26, broke sharply higher as Oracle’s implications digested, and hit an intraday high of $1,895 before settling at $1,881.51 on volume of 13.4 million shares.

The move is grounded in fundamentals. SanDisk’s most recent quarter posted revenues of $5.95 billion — up 97% sequentially — beating its own guidance. Q4 guidance calls for $7.75–$8.25 billion in revenue and EPS of $30–$33. Zacks carries the stock as a Rank #1 Strong Buy, and estimated current-year EPS growth stands at +2,096.7%.

The broader chip complex surged in sympathy — KLAC +12.92%, LRCX +12.65%, MU +11.66%, ARM +11.32% — making semiconductors the dominant theme of the session.

Adding macro fuel, President Trump announced that Iran’s supreme leader had approved a peace deal and that the Strait of Hormuz would reopen upon signing, lifting the Dow roughly 1,000 points intraday. Iran’s state media reportedly contradicted the claim, leaving the situation unresolved, but the peace signal was enough to sustain a broad risk-on rally — with the S&P 500 and Nasdaq 100 rising strongly .
