Cathie Wood Says the Memory Chip Trend Is Up but the Cycles Are ‘Vicious’
ARK Invest's Cathie Wood warned about volatility in memory chip makers like Micron (MU) and SanDisk (SNDK) due to competition, particularly from China. Both stocks have seen significant gains but recent declines. Micron's Q4 2026 gross margin was 87.0%, up from 45.7% a year earlier. SanDisk's margin rose to 84.6% in Q4 2026 from 22.5% in Q3 2025. Both companies have long-term contracts to mitigate downturns.

The 30-second read
Why it matters
New guidance provides fresh valuation data for two large memory chip makers, likely influencing short‑term price action.
Market read
Guidance updates for MU and SNDK are the primary trading catalysts; sector peers may be affected by the same macro‑cycle dynamics.
What to watch
Potential supply constraints from Chinese entrants like CXMT could support pricing despite modest guidance.
Background
Cathie Wood warned about volatile memory cycles while both Micron and SanDisk posted strong year‑to‑date gains. The article recaps new FY2027 guidance and mentions competitive pressure from CXMT.
Ticker impact
Micron disclosed FY2027 Q1 revenue guidance of $61.5B ± $1.5B and non‑GAAP EPS $38.15 ± $1.00 in an 8‑K filing.
potential downside as investors reassess valuation
Guidance numbers are new and materially affect valuation expectations for a large‑cap memory chip maker.
SanDisk provided FY2027 Q1 revenue guidance of $10.30B‑$10.80B and non‑GAAP EPS $44.00‑$46.00 in its latest filing.
potential downside as market prices in guidance
New guidance for a high‑growth memory vendor is material for short‑term trading.
Market effects
Memory‑chip sector may see broader valuation adjustments as guidance tempers expectations.
U.S. tech and semiconductor indices could face slight pressure.
Limited to memory‑chip manufacturers and related supply‑chain participants.
Counterpoint
If demand for AI‑driven workloads accelerates faster than expected, the guidance may be seen as a floor rather than a ceiling.
