Memory Chip Rally Splinters: DRAM Holds Firm While NAND Weakens
TREE NEWS reports: The memory chip sector is showing signs of divergence after a powerful rally. Bank of America (BofA) analysts warned in a November 13 report that the NAND flash market is weakening, with spot prices falling sharply, while DRAM prices remain resilient. This marks a shift from the broad-based upcycle that has lifted memory stocks by over 100% this year.
What Happened
NAND spot prices have dropped significantly: 512Gb wafer prices fell over 10% week-over-week to $14.3, and 1Tb wafers declined by mid-single digits to $24.9. Since mid-October, NAND spot prices have corrected by about 20%. In contrast, 16Gb DDR5 spot prices held steady at $60.2, up 150% year-over-year. BofA notes three warning signals for NAND: the spot price correction, weakening orders from PC and smartphone OEMs and Chinese hyperscalers, and potential delays in Q1 2027 contract price negotiations. Meanwhile, DRAM contract prices continue to rise, with 16Gb DDR5 up 5% month-over-month in October and server DDR5 modules surpassing $1,000.
Market Implications
The divergence has significant implications for memory stocks. BofA maintains a cautious view on NAND, forecasting a 5-10% sequential decline in IT NAND prices for Q1 2027, versus consensus expectations of a 10%+ increase. For DRAM, BofA expects price increases to continue through Q4 2026 (+8% QoQ) and Q1 2027 (+5% QoQ). This outlook favors companies with higher DRAM exposure, such as SK Hynix and Samsung, over NAND-focused players like SanDisk and Western Digital. The valuation gap is stark: SK Hynix trades at 3.6x 2026 P/E, Samsung at 4.7x, while Micron at 10.7x. NAND players like SanDisk trade at 4.3x 2027 P/E but face earnings risk.
Investor sentiment improved this week, with many seeing limited downside for DRAM-heavy stocks due to resilient AI data center demand, ongoing DRAM price increases, and low valuations. Samsung’s investor meeting on November 12 reinforced this: management expressed optimism on HBM and DRAM long-term agreements but gave conservative HBM market share targets of 30-40% and noted that LPDDR5 remains more profitable than HBM, suggesting no aggressive capacity shift. Samsung also gave a less optimistic outlook for IT NAND compared to enterprise SSDs, aligning with BofA’s cautious stance.
Key Takeaways for Investors
- DRAM remains the safer bet: AI data center demand and HBM capacity crowding out traditional DRAM supply support continued price increases. Companies with high DRAM exposure offer better risk-reward.
- NAND faces near-term headwinds: Spot price weakness, order softness, and potential delay in contract negotiations could pressure NAND pricing and earnings. The market may need to reprice NAND stocks downward.
- Valuations are attractive but divergent: Memory stocks trade at low multiples compared to AI semiconductor peers, but the earnings outlook varies. DRAM players are cheap with stable earnings; NAND players are cheap but face downgrades.
- Watch Q1 2027 contract negotiations: The timing and outcome of contract price talks will be crucial. If negotiations are delayed, NAND makers could lose pricing power.
- Samsung’s conservative HBM stance: While HBM demand is strong, Samsung’s restrained capacity expansion plans suggest less cannibalization of DRAM supply, supporting DRAM prices.
Overall, the memory upcycle is not over, but it is becoming more selective. Investors should favor DRAM-levered names and approach NAND with caution until pricing stabilizes.
