SanDisk Joins the Nasdaq-100 and the Passive Bid Hasn't Even Started Yet

The Nasdaq-100 Bid

Nasdaq announced on April 11 that SanDisk will replace Atlassian in the Nasdaq-100 effective April 20. The index is tracked by over 200 investment products managing more than $600 billion in assets globally, and every one of them needs to own SNDK by the rebalance date. That's not discretionary buying — it's mechanical.

The timing matters. SNDK was already the best-performing S&P 500 stock of 2025, up roughly 2,400% from its $40 IPO price in May 2025. Adding forced passive demand on top of that momentum creates a setup where the stock can grind higher on flow alone, regardless of whether fundamental buyers step in. The 21% weekly gain heading into the announcement suggests the front-running is already well underway, with institutional players like SG Americas ($108M position) and Vaughan Nelson ($16M) building exposure ahead of the switch.

Atlassian getting dropped is its own story — a software company replaced by a memory chip maker in the index that's supposed to represent the Nasdaq's heavyweights. It's a clean read on where the market thinks AI capex dollars are actually flowing: not to dev tools, but to the physical layer.

Bernstein's $3,000 Blue Sky

Bernstein analyst Mark Newman raised his SanDisk price target to $1,250 from $1,000 — the highest on Wall Street — and laid out a scenario where the stock could reach $3,000. The math: base-case FY27 EPS of $144 at an 8.7x multiple gets you to $1,250. Apply a 13x multiple to bull-case earnings of $224, and the blue-sky target approaches $3,000.

The thesis rests entirely on NAND pricing. Newman noted that prices only began inflecting meaningfully six to seven months ago and that the industry remains structurally undersupplied. SanDisk raised NAND flash prices by more than 10% effective April 1, and Q2 contract prices are expected to jump 70-75% versus Q1. The company can raise prices because AI data center demand is outstripping supply — a dynamic Newman dismissed TurboQuant concerns as doing nothing to change, calling the selloff "overdone."

This is now the third major analyst endorsement in two weeks, after BofA held its $900 target and Cantor Fitzgerald raised to $1,000. The consensus is hardening around a simple idea: NAND is the bottleneck for AI infrastructure, and SanDisk is the pure-play way to own it.

The April 30 Risk

The obvious question is what happens after the passive bid clears on April 20 and the earnings call arrives on April 30. Consensus expects $13.90 EPS on $4.61 billion in revenue — versus a $0.30 loss and $1.70 billion a year ago. Those are enormous numbers, but Bernstein's Q3 estimate of $14.18 and Q4 estimate of $25.30 suggest the real question is whether guidance accelerates from here or merely confirms what the stock has already priced.

The RSI sits near 68 — not flashing overbought yet, but getting close after a 2,400% run. The broader backdrop isn't clean either: geopolitical risk around a potential U.S. blockade of the Strait of Hormuz pressured markets on April 13, and SNDK gained against that tape, which is impressive but also means it's absorbing a lot of good news at once.

The setup for a post-inclusion pullback is textbook — buy the rumor, sell the rebalance — but the NAND pricing cycle gives longs a fundamental anchor that most index-inclusion trades lack. If April 30 earnings come in above the street and guidance points to the $25+ quarterly EPS trajectory Bernstein is modeling, the pullback probably gets bought. If not, a stock that went from $40 to $1,000 in fourteen months has room to give some back.
