SanDisk has emerged as a market darling this month, with Jim Cramer championing the stock for an extended period. His bullish stance has proven profitable so far.

Sandisk Corporation, SNDK

SNDK shares have rocketed 2,739% during the trailing 12-month period. Year-to-date for 2026, the equity has gained 246.06%, settling at $952.50 on April 14. After-hours activity pushed the price up an additional 2.47% to $976.

During commentary on the market’s positive response to the Iran ceasefire announcement, Cramer highlighted several memory sector players — SanDisk, Western Digital, Lam Research, and Seagate — emphasizing that demand for their offerings has reached extraordinary levels.

While bullish, Cramer’s remarks included criticism. He characterized SanDisk and Western Digital as “a tax on the system,” noting their ongoing price increases stem from supply constraints that can’t match demand. He described memory technology as having “low intellectual property” value and contributing to higher data center construction costs across the industry.

Despite these reservations, Cramer confirmed the underlying demand narrative holds weight. Data centers require substantial memory capacity, and current supply falls short. This imbalance has been the primary driver behind SNDK’s explosive performance.

Index Addition Creates Buying Pressure

A significant technical event approaches. SNDK’s addition to the Nasdaq-100 is scheduled for April 20. This inclusion mandates that passive index funds purchase shares, creating substantial institutional buying pressure.

Historically, such forced purchasing activity tends to elevate stock prices surrounding inclusion dates. However, some market observers consider this event a potential short-term peak rather than a launching pad, as it may trigger sell-the-news dynamics once mandatory buying concludes.

The rally isn’t purely speculative momentum. SNDK manufactures NAND flash memory and enterprise-grade solid-state drives — precisely the components hyperscale cloud providers and data center operators require in massive quantities.

With AI infrastructure investment remaining robust, the company has directly benefited from this spending wave. This demand is reflected in both revenue projections and share price appreciation.

Infrastructure Slowdown Presents Downside Scenario

Counterbalancing forces exist. Numerous ambitious data center projects unveiled following ChatGPT’s mainstream emergence have experienced delays or complete cancellations.

The explanations are diverse — community resistance, overly optimistic schedules, and mounting skepticism about AI’s actual business value. Multiple surveys conducted in early 2026 indicated that organizations implementing AI solutions experienced minimal or zero productivity improvements.

Should data center development activity decelerate significantly, the demand catalyst supporting memory manufacturers like SanDisk could diminish. A substantial portion of the stock’s valuation expansion rests on anticipated large-scale hardware purchases from enterprise customers.

As of April 14, SNDK was changing hands at $976 during extended trading, with its Nasdaq-100 debut approaching in just six days.
