2 AI Stocks That Didn't Get the Memo That the Bull Market Hit a Speed Bump

Palantir's AI Platform has driven accelerating revenue growth (70% year-over-year last quarter and accelerating over 10 quarters), but the stock trades at an expensive forward P/S of ~51x. Sandisk, spun out from Western Digital, is benefiting from surging NAND (flash) prices due to supply constraints and trades at a cheap forward P/E of ~8x on fiscal 2027 estimates; its upside depends on cyclical NAND recovery and adoption of its HBF tech with SK Hynix. Geopolitical tensions (U.S. conflict with Iran) support Palantir's government demand; overall fundamentals are constructive but valuations and cyclicality warrant caution.

Analysis

Palantir’s productization of data-to-ontology plumbing is the leverage point investors under-appreciate: once a customer’s operational ontology and asset linkage are embedded, churn and incremental monetization of adjacent AI modules become asymmetric. That creates a staged monetization path (services → platform fees → outcome-linked revenue) where near-term growth can outpace cash conversion, but long-term margins hinge on automation of deployment and reduction of bespoke services.

For Sandisk, the current pricing regime for NAND is less a short-term overshoot and more a structural rebalancing driven by capex reallocation toward specialized AI memory (HBM/HBM-adjacent). If NAND suppliers maintain conservative wafer starts for another 3–12 months, flash ASPs could remain elevated; conversely, a modest capex re-expansion or a demand shock from consumer devices would quickly compress spreads given NAND’s high fixed-cost structure.

Geopolitical tailwinds (defense spending, onshoring of critical data infrastructure) amplify platform winners domestically but add concentration risk: vendors with a single large public-sector anchor face lumpy renewals and increasing scrutiny on pricing and export controls. Simultaneously, AI-driven server demand diverts capital into HBM, creating a two-tier memory market that benefits focused flash specialists but increases counterparty and inventory timing risk for OEMs.

Key catalysts to watch on 0–24 month horizons are: FY guidance seasonality and book-to-bill on commercial deployments, NAND wafer-start cadence and ASP guidance from suppliers, and any near-term government procurement awards or export-control moves. These will determine whether current valuations price in sustainable platform economics or a cyclical revenue surge that reverts within 4–8 quarters.

Key Decisions for Investors

• Long PLTR via calendar/LEAP spread: buy 12–18 month OTM LEAP calls (target ~+100–150% strike) financed by selling 3–6 month calls to capture immediate premium; entry on a <=20% pullback from current levels. Risk: full premium; Reward: capture multi-quarter platform monetization with 2–3x+ upside if commercial take-rates accelerate.
• Pair trade — Long SNDK / Short WDC exposure: tactically long SNDK equity or 6–12 month call spread to play sustained NAND ASPs and HBF optionality, paired with short WDC (or short WDC call) to hedge broader HDD/NAND cyclic exposure. Timeframe 6–12 months; target asymmetric 1.5–2.5x upside vs limited carry cost on short.
• Event hedge for PLTR: buy 3–6 month downside protection (puts) sized to cover 25–40% of position value ahead of major budget/contracting windows or earnings to protect vs lumpiness in public-sector renewals. Cost accepted as insurance against 1–2 quarter revenue shocks.
• Volatility trade on NAND cycle: sell near-term volatility via short-dated strangles on smaller-cap NAND suppliers if ASPs remain stable for 2–3 quarters, but hedge with long-dated calls on SNDK to maintain convex upside if HBF adoption proves structural. Maintain position size so that long calls cover gamma risk.
