SanDisk has emerged as a dominant market performer this month. Jim Cramer has consistently championed SNDK for several months, and his position has proven profitable.
The trailing 12-month period shows SNDK climbing 2,739%. During 2026 specifically, shares have advanced 246.06%, settling at $952.50 on April 14. Extended trading that evening brought another 2.47% increase, pushing the price to $976.
Cramer referenced the stock while analyzing the market bounce following the Iran ceasefire announcement. He highlighted several memory-focused companies — SanDisk, Western Digital, Lam Research, and Seagate — emphasizing that product demand has reached exceptional levels.
His remarks carried some criticism alongside the positive outlook. Cramer characterized SanDisk and Western Digital as “a tax on the system,” explaining that persistent price increases stem from supply constraints. He mentioned that memory represents “low intellectual property” and contributes to elevated data center construction costs across the industry.
Despite these concerns, he confirmed the underlying demand narrative holds substance. Data center operators require substantial memory capacity, and current production falls short. This supply-demand imbalance has fueled the SNDK appreciation.
Index Addition Scheduled for April 20
A technical catalyst now appears on the horizon. SNDK receives Nasdaq-100 membership on April 20. Following this addition, passive funds tracking the index must acquire shares, creating substantial institutional buying pressure.
Historical patterns show such mandatory purchasing typically elevates stock prices surrounding inclusion dates. Certain market observers consider this event a potential short-term peak rather than a launching point, since it may produce a sell-off once the required buying concludes.
The stock’s advance rests on genuine business drivers beyond simple price momentum. SNDK produces NAND flash memory and enterprise solid-state drives — precisely the components that cloud providers and data center operators require in substantial quantities.
Given the ongoing elevated spending on AI infrastructure, the company has captured significant benefits. This demand manifests in both projected revenue figures and equity valuations.
Construction Postponements Present Notable Concerns
Certain indicators suggest potential challenges ahead. Numerous ambitious data center initiatives announced following ChatGPT’s public introduction have experienced delays or complete abandonment.
The contributing factors span multiple areas — community resistance, overly optimistic schedules, and mounting skepticism regarding AI’s actual business value for adopting organizations. Multiple early-2026 research studies indicated that enterprises implementing AI technologies observed minimal or zero productivity improvements.
Should data center development activity experience meaningful deceleration, the favorable demand environment for memory manufacturers like SanDisk might deteriorate. Substantial portions of the stock’s valuation expansion have been predicated on anticipated large-scale hardware procurement from enterprise customers.
As of April 14, SNDK reached $976 during after-hours activity, with the Nasdaq-100 incorporation arriving within six trading days.
