Analysis of Memory Industry Cycle Inflection Point
DRAM Contract Prices Rise for Two Consecutive Quarters
From an industry cycle perspective, the memory chip market is experiencing a critical inflection point. According to the latest TrendForce data, DRAM contract prices rose by 8% quarter-on-quarter in the second quarter of 2026, marking the second consecutive quarter of increases, indicating that the industry has officially exited the downward cycle and entered a new upward channel.
This cyclical change is mainly influenced by factors from both supply and demand sides. In terms of supply, major memory manufacturers implemented strict capacity control between 2025-2026, reducing capital expenditures and limiting new capacity expansion. On the demand side, emerging applications such as AI, cloud computing, and 5G continue to drive storage demand growth, especially for high-performance storage that exceeds expectations.
Inventory Adjustment and Price Recovery
After inventory adjustments in 2024-2025, the memory chip industry has entered a healthy destocking phase. According to industry statistics, inventory turnover days for major DRAM manufacturers have decreased from over 70 days in mid-2025 to around 45 days currently, approaching historical healthy levels.
The optimization of inventory structure has created favorable conditions for price recovery. SK Hynix specifically mentioned in its latest financial report that the company has controlled DRAM inventories at reasonable levels, enabling rapid response to market changes and seizing profit growth opportunities from price increases.
Competitive Landscape with Samsung Electronics
In the Asian memory chip US stock market, the competitive landscape between SK Hynix and Samsung Electronics has attracted significant attention. Recently, the ADR performance of the two companies has shown clear divergence, with SK Hynix reaching new highs while Samsung Electronics has been dragged down by traditional DRAM business, showing relatively weak performance.
This divergence mainly stems from different choices and progress in HBM technology routes between the two companies. SK Hynix has focused on R&D and mass production of HBM4, while Samsung Electronics has simultaneously invested in both HBM3E and HBM4, leading to resource dispersion. According to supply chain sources, Samsung Electronics' HBM4 yield is currently still about 15 percentage points lower than SK Hynix's, which constrains its market competitiveness and customer acquisition capabilities.
However, it is worth noting that Samsung Electronics still maintains a leading position in traditional DRAM, especially with a strong customer base in PC and server markets. Industry analysts believe that competition between the two companies will continue long-term, with HBM technology being just the current focus, and fierce competition expected to continue in emerging storage technology fields in the future.
