SanDisk stock slides 14% as AI chip selloff overshadows bullish calls

SanDisk (SNDK) shares fell 14% intraday to a session low of $1,707.58 as investors rotated out of AI chip/memory hardware into AI software. The drop follows an extraordinary H1 2026 rally (+~858%), leaving the stock vulnerable to profit-taking after sentiment shifted.

Analysis

This looks like a positioning event first and a fundamentals event second. After an extreme multi-month run, the marginal buyer is no longer a fundamental long-only manager but a momentum or factor flow; once that bid fades, any stock tied to a cyclical input chain gets hit harder than software because there is no recurring-revenue cushion to defend the multiple.

The second-order risk is that this is not isolated to one name: a sustained move away from AI infrastructure toward software would pressure the entire memory complex and nearby beneficiaries of AI capex, even if unit demand remains healthy. In the near term, the tape can overshoot by another 10-20% on forced de-risking; over 1-3 months, the key variable is whether memory pricing and gross-margin commentary keep improving enough to overpower the valuation reset.

Contrarianly, the market may be overconfident that software is the only "clean" AI exposure. If hyperscaler spend stays elevated, memory and storage remain bottlenecks, and that can reassert itself in the next earnings cycle. The move is likely reversible only if the next print shows softer pricing, weaker backlog, or management turns cautious on the pace of AI-related demand; absent that, this is more likely a multiple compression pocket than a broken thesis.

Key Decisions for Investors

• Avoid buying the first sharp dip in SNDK; wait 2-4 weeks for post-flow stabilization, then only add if price reclaims the prior breakdown area on above-average volume. Falsifier: continued heavy-volume selling and lower highs.
• Use a short-dated put spread on SNDK to express a further de-grossing move over the next 2-6 weeks. Best risk/reward is if the stock fails to recover after the first bounce; exit if it reclaims the full selloff.
• Pair trade: long IGV or a software-heavy AI basket vs short SNDK for 1-3 months to isolate the rotation from hardware to software. This works best if market leadership continues to favor duration and multiple expansion over cyclicals.
• If you want to stay constructive on AI hardware, prefer waiting for next-quarter memory pricing and margin data before adding exposure. A stable-to-up gross margin guide is the key trigger that would invalidate the rotation thesis.
• Set an alert on memory ASP trends and hyperscaler capex commentary; if both remain firm, the selloff is likely a positioning reset and not a structural top, making a tactical long-entry more attractive on any further 10%+ drawdown.
