SanDisk experienced a dramatic price surge following confirmation of its upcoming addition to the prestigious Nasdaq-100 index, where it will take the place of Atlassian in a rebalancing move that has captured significant market attention. Shares jumped by as much as 11% during the trading session, building upon an existing upward trend driven by robust appetite for AI-powered data storage solutions.
The company’s entry into the index becomes official before markets open on April 20, setting the stage for substantial share purchases by major index-tracking investment vehicles. This mechanical buying will likely come from more than 200 investment products with combined assets exceeding $600 billion that mirror the Nasdaq-100’s composition.
Index Tracking Funds Drive Buying Pressure
Joining a major index like the Nasdaq-100 carries concrete, tangible consequences beyond prestige. The addition mandates that passive investment vehicles—including ETFs and index mutual funds—adjust their holdings to maintain accurate benchmark tracking, frequently resulting in concentrated purchasing activity over compressed timeframes.
This structural buying arrives as SanDisk already benefits from investor enthusiasm for AI infrastructure investments. Market momentum has increasingly tilted toward hardware manufacturers and storage providers as artificial intelligence computing demands escalate throughout cloud platforms and data center operations.
Simultaneously, software companies have encountered headwinds amid mounting concerns that AI technologies could fundamentally disrupt established business frameworks. The index composition change mirrors this widespread market transition from software-concentrated portfolios toward tangible infrastructure underpinning AI expansion.
Artificial Intelligence Drives Storage Requirements
The stock’s upward movement also stems from robust operational fundamentals connected to artificial intelligence applications. SanDisk has capitalized on escalating needs for advanced memory solutions and storage architecture essential for AI model training and deployment processes.
Recent company forecasts indicated fiscal third-quarter revenue ranging from $4.4 billion to $4.8 billion, accompanied by adjusted earnings per share estimates between $12 and $14—figures that exceeded Wall Street consensus. Management attributed this performance primarily to heightened demand from data center clients expanding AI computing capabilities.
Financial analysts have responded with notably increased price projections. Bernstein analyst Mark Newman elevated his target to $1,250, while Cantor Fitzgerald’s C.J. Muse raised expectations to $1,000, emphasizing beliefs that constrained NAND flash memory availability could continue for extended periods.
Supply Chain Challenges and Market Dynamics
Industry executives are increasingly vocal about unprecedented challenges AI growth presents for storage production capabilities. Nvidia CEO Jensen Huang recently emphasized that storage infrastructure will likely encounter substantial capacity constraints as artificial intelligence deployment expands across sectors.

Storage sector leaders have similarly projected that supply limitations may persist through the coming decade. Consumption from hyperscale cloud operators and AI technology developers continues surpassing manufacturing output, generating a fundamental mismatch within semiconductor storage markets.
This favorable supply-demand dynamic has elevated investor optimism across comparable companies, including Western Digital, Seagate Technology, and Micron Technology, all positioned within the same growth trajectory.
Software Sector Struggles as Atlassian Departs
Complementing SanDisk’s index entry is the departure of Atlassian from the benchmark. Software equities have encountered considerable challenges throughout 2026, with sector-wide indices experiencing notable declines as market participants recalibrate growth assumptions within an AI-centric environment.
Industry observers have highlighted growing apprehension that AI applications may erode profit margins or fundamentally alter conventional software revenue structures. Atlassian’s removal represents both index rebalancing mechanics and evolving investor preference toward infrastructure-focused AI beneficiaries.
