(SeaPRwire) –   SanDisk is moving to the Nasdaq 100, a development that triggered an immediate investor response. Shares of the flash memory manufacturer gained 1.8% to reach $866.90 in Monday’s pre-market session after Nasdaq confirmed the addition, which is set to take place before the market opens on April 20.

SanDisk Corporation, SNDKV

This transition marks the culmination of an extraordinary period for SNDK. The stock has climbed 259% so far in 2026, and it has rallied 2,439% over the past year. This growth is primarily attributed to the high demand for NAND flash memory required for AI data center infrastructure.

SanDisk will take over the position currently held by Atlassian (TEAM), which has experienced a difficult year. TEAM shares have plummeted 65% in 2026, impacted by concerns that AI-based tools are disrupting the software industry.

Why Index Inclusion Matters

When a company is added to a major index like the Nasdaq 100, index-tracking funds and ETFs are obligated to modify their portfolios to reflect the new list. This buying activity can provide a significant boost to a stock’s price around the time of its inclusion.

The overall market environment was less optimistic on Monday. S&P 500 futures dropped 0.6% after President Trump initiated a blockade of the Strait of Hormuz, causing concern among investors.

For SanDisk, being part of the Nasdaq 100 validates its status as a major technology holding. The influx of passive capital may make the stock more sensitive to general tech sector trends rather than just company-specific developments.

The SanDisk narrative has been centered on limited NAND supply and the surge in AI data center needs. Consequently, analysts have issued several price target upgrades. Its inclusion in the index places it alongside the most prominent tech companies in the U.S. market.

Atlassian Takes the Hit

Atlassian’s departure from the Nasdaq 100 illustrates how quickly market dynamics can change. The Australian software firm has seen its valuation decline as investors fear that AI-native solutions will challenge its collaboration software business.

TEAM shares fell 3% on Monday, adding to its year-to-date losses for 2026.

The rebalancing is set for April 20. Starting then, institutional investment vehicles that track the Nasdaq 100 will be required to include SanDisk in their holdings.

Analysts have also pointed out potential risks for SanDisk. A possible transition from a NAND shortage to an oversupply, along with the growing influence of major cloud customers, could put pressure on profit margins. Nevertheless, earnings growth projections remain positive for the time being.

SanDisk already competes for investor interest with memory rivals like Micron and Samsung. Joining the Nasdaq 100 places it on a much larger stage. The company’s performance in its next earnings report—and its commentary on NAND pricing and supply—will be under greater scrutiny from a wider benchmark-focused audience.
