SanDisk Falls 5% Before NASDAQ 100 Debut: Is the Short Squeeze Running Out of Steam?

SanDisk (NASDAQ:SNDK) stock is down 5% in early trading on April 14, pulling back toward $900 after closing yesterday at $952.50. The retreat comes just days before the company’s scheduled entry into the NASDAQ 100 on April 20, replacing Atlassian (NASDAQ:TEAM) stock.

That kind of pullback would barely register for most stocks, but for SNDK, it’s worth watching closely. The stock has surged 286% year-to-date, fueling intense debate over whether the run is fundamentally justified or dangerously overextended.

Today’s dip looks like profit-taking ahead of the index debut rather than any shift in the underlying story. No new negative catalysts have emerged, and the fundamental case for SanDisk remains intact. Still, with momentum stocks trading at these levels, even a small crack draws attention.

NASDAQ 100 Debut Triggers Buy-the-Rumor, Sell-the-News Trade

SanDisk’s upcoming NASDAQ 100 inclusion has been a powerful catalyst. Index funds and ETFs tracking the NASDAQ 100 are required to purchase SNDK shares ahead of the April 20 rebalancing, and that forced institutional buying has layered on top of an already aggressive short squeeze dynamic.

Today’s 5% pullback may simply be traders locking in gains before the event date arrives.It’s a classic buy-the-rumor, sell-the-news setup.

Once the index inclusion is official and the forced buying is complete, the marginal buyer disappears. Whether the stock finds a new floor or continues lower depends heavily on what comes next from the fundamentals.

The RSI Is Flashing Caution

From a technical standpoint, SNDK entered overbought territory heading into today’s session. The 14-day RSI closed at 74.15 on April 13, up sharply from 56.9 on April 7. That’s a significant acceleration in momentum over just four trading days, and RSI readings above 70 historically signal elevated risk of a near-term pullback.

That said, SNDK stock has blown past these levels before. The RSI hit 95.32 in September 2025 and 89.30 in early February 2026 without triggering a sustained reversal. Today’s reading of 74 is elevated, but it’s well below those historical extremes, which means the technical picture alone doesn’t confirm the squeeze is finished.

The Fundamental Story Hasn’t Changed

For investors focused on the business rather than the tape, SanDisk’s trajectory remains compelling. NAND flash memory prices surged 60% in Q1, with an additional 70% to 75% increase anticipated in the current quarter. SanDisk is positioned directly in the path of that pricing tailwind, and its most recent results confirmed the leverage.

In Q2 FY2026, SanDisk reported revenue of $3.025 billion, up 61% year over year, with non-GAAP EPS of $6.20 against an estimate of $3.54. Free cash flow reached $980 million. For Q3 FY2026, the company guided for revenue of $4.4 billion to $4.8 billion and adjusted EPS of $12 to $14, with earnings due April 30.

SanDisk also extended its manufacturing joint venture with Kioxia until 2034 and invested $1 billion in Nanya Technology, acquiring a 3.9% stake and securing a multi-year DRAM supply agreement. These moves point to a company building durable supply chain advantages, not just riding a cyclical wave.

Wall Street Remains Divided on Valuation

SanDisk stock analyst price targets span a wide range, reflecting genuine disagreement about where the fair value sits. Bernstein raised its target to $1,250, while Mizuho carries a $1,000 target with a Buy rating and Citi sits at $980. On the more cautious end, Morgan Stanley holds a $690 target despite a Buy rating, and BofA pegs fair value at $900.

The composite sentiment score from news and social signals sits at 71.09, rated bullish with medium confidence. Reddit sentiment for SNDK scored 68 out of 100, leaning bullish, though activity remains relatively light. One post in r/stocks captured the mood well: “SNDK still looks strong, just trading the bands for now.”

The SNDK stock bulls point to AI-driven storage demand and index rebalancing inflows as durable tailwinds. Meanwhile, the bears argue the valuation has outrun the fundamentals. With earnings due April 30, that debate is about to get a fresh data point. Watch for whether today’s pullback stabilizes near the $900 level or accelerates into the index debut date.
