Jim Cramer Says AI Stocks Micron and Sandisk (Up Over 600% Since January 2023) Can Go Even Higher

Strong AI-driven memory demand and an industry-wide equipment-driven supply shortage underpin bullish views on memory-chip names: Micron reported fiscal Q1 2026 revenue of $13.6 billion (+20%), non-GAAP gross margin expansion of 17 percentage points and adjusted EPS of $4.78 (+167%), while gaining ~10 percentage points of HBM share; Wall Street models a 37% annual EPS CAGR to FY2029 and values the stock around 32x forward earnings. Sandisk posted fiscal Q1 revenue of $2.3 billion (+23%) but saw non-GAAP EPS fall 33% to $1.22 with management forecasting a near triple sequential recovery; despite a projected 79% EPS CAGR to FY2029 the stock trades near 170x forward earnings after a ~1,050% run since its spin. The takeaway for allocators is differentiated risk/reward: Micron appears reasonably valued given market-share gains and AI exposure, whereas Sandisk looks stretched after its steep rally.

Analysis

Market structure: AI-driven data-center demand is creating a multi-quarter supply shortfall in DRAM/HBM and NAND; winners include Micron (MU) and select enterprise SSD vendors that secure hyperscaler design wins, while commodity HDD suppliers and legacy low-margin NAND suppliers lose pricing power. Micron's 10-pp HBM share gain and 625% stock rise since Jan‑2023 imply durable pricing leverage; Sandisk's (SNDK) 1,050% run and 170x forward multiple price near-term optimism into long-term performance.

Risk assessment: Key tail risks are a rapid capex catch-up by Samsung/SK Hynix within 12–18 months, a sudden hyperscaler inventory drawdown, or new export controls cutting access to key customers—each could erase 30–60% of excess margin in 6–12 months. Short-term (days/weeks) volatility will be earnings- and guidance-driven; medium-term (3–12 months) depends on equipment lead times (6–18 months) and multi-year structural AI demand through 2029.

Trade implications: Favor selective long in MU sized 2–3% of equity risk with a 12‑month horizon while using call spreads to cap premium; avoid outright long SNDK or reduce exposure, instead consider short or put structures given 170x valuation and stretched sentiment. Implement pair trades (long MU, short SNDK) to capture relative share gains; hedge sector beta via semiconductor equipment longs only if you see confirmed capex acceleration.

Contrarian angles: Consensus understates how fast hyperscalers can shift supply via custom contracts—winners may be hyperscaler-favored suppliers, not broad-market leaders. The market may be too sanguine on SNDK's near-term tripling of EPS; a 20–40% mean-reversion is plausible if sequential guidance disappoints. Unintended consequence: elevated margins now will invite aggressive capex that flips scarcity to oversupply in 12–24 months, pressuring current multiples.

Key Decisions for Investors

• Establish a 2–3% long position in MU (equity) within 2–4 weeks; supplement with a 9–12 month call spread to target ~30–50% upside while limiting premium; add more on pullbacks of 8–12% and use a 15% stop-loss from entry.
• Avoid entering new outright long positions in SNDK while it trades >150x forward earnings; consider buying 3–6 month puts or selling 3–6 month call spreads if trading on strength, targeting a 30–50% downside capture if sentiment reverses.
• Implement a pair trade: long MU 2% vs short SNDK 1–1.5% (dollar-neutral) to express relative fundamentals; rebalance after each earnings release (next 90 days) and close pair if MU outperforms SNDK by >25% or if SNDK guidance validates growth.
• Monitor four near-term catalysts over the next 90–180 days: (1) hyperscaler SSD/HBM design-win announcements, (2) quarterly revenue/margin guidance vs. Street, (3) capital-equipment lead-time disclosures, and (4) any export-control or subsidy policy changes—take profits or widen hedges if two catalysts turn negative.
