SanDisk Corp (SNDK) surged 24.13% to $1261.04 on Thursday, driven by a broad rally in memory and chip stocks. The move followed a sharp intraday gap up of 1.9% and a steady climb through the session. Analysts and traders are attributing the rally to renewed optimism in the sector amid speculation about AI-driven demand and broader market rotation into tech.

What Happened

SNDK opened at $1034.78, well above the previous close of $1015.89, and continued to climb throughout the session. The stock reached an intraday high of $1268.40 at 10:30 AM ET before settling near $1261.31. The move was part of a broader upswing in chip and memory stocks, including Micron, SK Hynix, and Western Digital. Recent coverage has highlighted the sector’s potential amid AI storage demand and long-term industry deals. A new theory circulating among investors appears to have reignited interest in SanDisk, reversing a recent trend of declining sentiment and price.

What The Data Shows

The stock’s 24.13% gain came on a volume of 10.9 million shares, which is 0.7 times its 3-month daily average. This suggests a moderate but concentrated buying interest. The price has swung dramatically in recent months, falling 29.1% over the last eight sessions before today’s reversal. The 52-week range of $40.10 to $2354.39 shows the stock remains volatile. Additionally, unusual options activity has been noted, with $62.3 million in call premiums traded and no put premiums. The largest single options print totaled $17.0 million. Insiders have sold $12,000 worth of shares in the last 90 days, while members of Congress have made several small purchases.

What To Watch

SNDK is not scheduled to report earnings in the immediate future. Investors should monitor the breadth of the chip stock rally and whether the sector can sustain its upward momentum. Broader coverage and sentiment shifts could also influence the stock’s next move.
