担忧清单越来越长，存储价格还能涨多久？

Group 1 - The core view of the article is that the storage chip industry remains fundamentally strong, with a price increase cycle expected to last until 2027, despite growing concerns about potential risks [2][3][7]. - Investors are generally optimistic about the storage industry, driven by strong AI demand and improving profitability, although concerns about various risks have increased compared to a few months ago [3][4][5]. - Key risks identified include potential slowdown in AI capital expenditures, weakening demand for smartphones and PCs, aggressive capacity expansion by storage manufacturers, and possible price declines in the spot market [4][6]. Group 2 - The report indicates that investors expect storage prices to continue rising at least throughout this year and possibly until 2027, supported by ongoing supply constraints [8]. - Concerns regarding NAND supply are notably higher than those for DRAM, primarily due to the lower technical barriers associated with NAND technology [9]. - Strong demand for HBM (High Bandwidth Memory) is anticipated to drive higher pricing, with particular attention on the demand outlook for HBM3E and HBM4 [10][11]. Group 3 - Capital expenditures in the storage industry are expected to exceed current market expectations due to tight supply-demand dynamics across DRAM, NAND, and HBM sectors [14]. - Investors are shifting their valuation preferences towards price-to-earnings (P/E) ratios rather than the traditional price-to-book (P/B) ratios, reflecting increased confidence in the sustainability of storage companies' profitability [14][16]. - Long-term supply agreements (LTAs) are expected to mitigate the demand volatility seen in previous cycles [16]. Group 4 - Samsung Electronics and SK Hynix are viewed positively by investors, with a growing preference for Samsung due to its larger exposure in the traditional storage market and advancements in HBM4 technology [17][18]. - SK Hynix is expected to maintain its leading market share in HBM, and potential ADR listings could enhance its valuation [19]. - Among non-storage companies, Samsung Electro-Mechanics has garnered significant attention due to a substantial stock price increase and growth opportunities in MLCC pricing and ABF substrate business [20].
