#分享美股交易赢英伟达股票 #存储芯片概念股逆势上涨 Optical communication and semiconductor sectors diverge, with leading stocks experiencing extreme ups and downs!

The optical communication sector has become a major casualty, with several leading stocks falling sharply. Lumentum dropped 5.2%, Coherent fell 4.8%, Applied Optoelectronics (AAOI) declined 6.2%, Credo decreased 5.1%. These optical device and high-speed interconnect chip manufacturers previously surged due to the explosive demand for 1.6T optical modules. This correction is mainly driven by profit-taking and valuation pressures. The semiconductor sector shows clear differentiation. Nvidia fell 3.62%, Broadcom declined 0.49%, AMD dropped 3%, with these AI chip and data center-related leaders experiencing adjustments. Meanwhile, the storage chip sector defied the trend and strengthened, with the Philadelphia Semiconductor Index reaching new all-time highs. The independent rally of storage chips is very impressive. SanDisk surged 6.71%, closing above $1,800 for the first time. Western Digital rose 5.51%, Intel increased 4.43%, Micron Technology gained 1.45%. Behind this divergence is a fundamental change in the demand structure for storage driven by AI data centers.
Why can storage chips outperform against the trend? AI demand is the core engine.
The rise of storage chips is not accidental but supported by solid fundamentals. The most core driver is the explosive demand for high-bandwidth memory (HBM) from AI data centers. Jensen Huang previously explicitly pointed out that storage is a key bottleneck for AI systems, and this judgment has become industry consensus. The supply and demand gap in the HBM market continues to widen. Institutions forecast that by 2026, HBM capacity will increase by about 50%, but demand growth will exceed 100%, making the supply-demand imbalance difficult to resolve in the short term. In Q3, the contract prices for some core storage categories are expected to increase by about 20% month-on-month, further supporting the performance of related companies. Micron Technology, as a storage leader, recently broke through a trillion-dollar market cap and remains a target for capital pursuit. Companies like SanDisk and Western Digital benefit from the growing demand for SSDs and mechanical hard drives in AI data centers, with order schedules extending to 2028. $MU
