- The stock is scheduled to enter the Nasdaq-100 index on April 20, creating automatic buying pressure from index funds

SanDisk has emerged as a market standout this month, with Jim Cramer championing the stock for several months. His bullish stance has proven profitable for followers so far.
SNDK shares have delivered a remarkable 2,739% return over the past year. Year-to-date in 2026, the stock has posted a 246.06% gain, finishing regular trading at $952.50 on April 14. Extended-hours activity pushed the price another 2.47% higher to $976.
During commentary on the market bounce following Iran ceasefire news, Cramer spotlighted a group of memory sector players — SanDisk, Western Digital, Lam Research, and Seagate — characterizing product demand as “off the charts.”
However, Cramer’s assessment wasn’t purely celebratory. He labeled SanDisk and Western Digital as “a tax on the system,” explaining that these companies continue pushing prices upward because supply remains severely constrained. Memory components, he observed, represent “low intellectual property” products that nonetheless make constructing data centers costlier for the entire industry.
Despite those concerns, Cramer confirmed the demand narrative is legitimate. Data center operators require massive memory volumes, and current production simply can’t satisfy that appetite. This supply-demand imbalance has been the primary engine behind SNDK’s extraordinary performance.
Index Addition Set for April 20
A significant technical event is rapidly approaching. SNDK is slated for Nasdaq-100 inclusion on April 20. This addition will compel passive index funds to purchase shares, creating a substantial wave of institutional buying activity.
Historically, this type of mandatory purchasing has propelled stocks upward during the period surrounding index entry. However, some market observers caution that the event could represent a short-term peak rather than a launch point, as it sometimes triggers sell-the-news behavior once the programmatic buying concludes.
The rally isn’t purely speculative momentum. SNDK[[/LINK_END_3]] manufactures NAND flash memory and enterprise solid-state drives — precisely the components that cloud hyperscalers and data center operators require in enormous quantities.
With artificial intelligence infrastructure investment remaining robust, SanDisk has positioned itself as a primary beneficiary. This demand surge is reflected in both forward revenue projections and the share price trajectory.
Construction Slowdowns Present Downside Risk
Not all signals are positive. A significant number of ambitious data center projects unveiled in the period after ChatGPT’s public release have experienced postponements or outright cancellations.
The explanations are diverse — community resistance, overly optimistic schedules, and mounting skepticism about whether AI implementation is actually generating returns for adopting businesses. Multiple surveys conducted in early 2026 indicated that organizations deploying AI technologies reported minimal or zero productivity improvements.
Should data center construction activity decelerate substantially, the demand catalyst supporting memory manufacturers like SanDisk could diminish. A considerable portion of the stock’s valuation expansion has been predicated on expectations for large-scale hardware procurement from enterprise customers.
As of April 14, SNDK was changing hands at $976 during after-hours trading, with Nasdaq-100 entry just six days away.
