SanDisk Joins Nasdaq-100 Today — Stock Up 300% Year-to-Date

Flash memory specialist SNDK officially joins the Nasdaq-100 index today, April 20, effective prior to market open.

Nasdaq announced on the 10th that SNDK would be added to the Nasdaq-100, replacing existing constituent TEAM. The Nasdaq-100 comprises 100 large-cap non-financial companies listed on Nasdaq and is tracked by more than 200 investment products worldwide, with total assets under management exceeding $600 billion.

Up 300% YTD, 50% in a Single Month

SNDK's price action has been extraordinary. Shares have surged roughly 50% in the month since the index inclusion announcement and are up nearly 300% year-to-date. On a trailing one-year basis, the stock has gained more than 2,500%. Current market capitalization stands at approximately $130–$140 billion.

The primary catalyst is explosive demand from AI data centers. SNDK's NAND flash memory and enterprise SSDs are critical storage components for AI workloads, and a tight supply environment has driven a sharp simultaneous rise in both pricing and margins.

Index Inclusion Triggers Mandatory Passive Buying

Joining the Nasdaq-100 carries structural implications beyond mere prestige — passive funds tracking the index, including QQQ, are required to add the new constituent to their portfolios. With $600 billion in assets now obligated to establish positions in SNDK, average daily trading volume has risen from approximately 17.5 million shares to over 19 million since the announcement.

Market participants broadly expect that the close of trading on Friday, April 18 — the last session before official inclusion — marked the peak of passive fund inflows. Going forward, fundamentals and earnings are expected to become the primary drivers of price performance, rather than technical supply-demand dynamics.

Q3 Earnings Report Is the Next Inflection Point

Wall Street analysts are rapidly raising their outlooks. Evercore ISI recently initiated coverage with an Outperform rating and a $1,200 price target, while Arete Research upgraded its target to $1,800. Citigroup and BNP Paribas have also raised their respective price targets.

The next key test is the fiscal Q3 earnings release scheduled for April 30. Consensus revenue estimates range from $4.4 billion to $4.8 billion, representing year-over-year growth of 159–182%. Non-GAAP EPS is expected in the range of $12–$14, with gross margins projected at 65–67%.

Some market observers flag a key risk: should the supply shortage ease, NAND prices could decline sharply, compressing margins significantly.
