The Sandisk Rally Isn't Over Yet

Sandisk says its fiscal 2026 Q3 revenue nearly doubled sequentially and net profit margins topped 60%, with management calling the quarter a "fundamental inflection point." The company guided to an $8 billion midpoint for fiscal 2026 Q4 revenue, implying 34.4% sequential growth, and remains sold out through 2026 amid AI-driven memory shortages. Despite a 4,850%+ rally over the past year, the article argues the stock still screens at a reasonable forward P/E of 30.6 versus 67.7 trailing.

Analysis

The setup is less about one company’s execution and more about a capital-allocation bottleneck across the AI stack: as compute expands faster than memory supply, pricing power migrates downstream to whoever controls scarce NAND bits. That tends to create a longer-duration earnings upgrade cycle than the market usually discounts, because even modest unit growth can translate into outsized margin expansion when utilization is tight and customers are locked in by qualification cycles.

The second-order effect is that memory scarcity can become self-reinforcing. Hyperscalers and OEMs will likely pull forward procurement to de-risk shortages, which tightens near-term supply further and extends the pricing tailwind into multiple budget cycles; meanwhile, weaker competitors may be forced to prioritize spot shipments over strategic customer relationships, accelerating share concentration. The risk is that this becomes a classic supply response story: if capex expands too aggressively, the market can move from shortage to glut in 12-18 months, and the stock’s multiple will compress before fundamentals roll over.

The consensus seems to be anchoring on a “cheap versus growth” framing, but the more important variable is durability of scarcity versus elasticity of replacement demand. If end demand for AI infrastructure slows even slightly, the high-margin, inventory-tight narrative can unwind quickly because memory is one of the most cyclical semis; conversely, if shortages persist into 2027 as management/peers imply, today’s forward multiple still understates normalized earnings power. For now the move looks under-owned on fundamental revision risk, but increasingly vulnerable to any sign of lead-time normalization or customer inventory digestion.

Key Decisions for Investors

• Stay long SNDK into the next earnings cycle, but size as a momentum-with-fundamentals trade rather than a core compounder; upside remains meaningful if FY26/FY27 guidance is revised up again, while downside is sharp if sequential growth decelerates.
• Buy SNDK Jan-2027 call spreads on pullbacks rather than chasing spot; this captures the multi-quarter scarcity thesis while capping premium burn if the memory cycle turns faster than expected.
• Pair trade: long SNDK / short INTC over 3-6 months. SNDK benefits directly from tight NAND supply, while INTC is more exposed to AI capex normalization and has weaker operating leverage to memory pricing.
• Take profits opportunistically on SNDK after large gap-up earnings reactions; the stock is now vulnerable to multiple compression if the market starts discounting a 2027 supply response.
• Use NVDA as a sentiment hedge rather than a direct alpha expression: if AI capex sentiment weakens, memory names typically derate first, but NVDA can absorb some of the broader AI multiple compression better than component suppliers.
