Memory semiconductor stocks have fallen 19 percent from their September peak, nearly erasing gains since July. UBS analysts argue that market concerns about future supply growth and competitive pressure are overdone, positioning the sector for meaningful upside.
The bank cites an average estimated free cash flow yield of 29 percent for 2027-2030 across its covered memory companies, excluding Chinese competitor ChangXin Memory Technologies. UBS maintains buy ratings on all stocks in its memory coverage universe, with Samsung Electronics (KS:005930) as its top pick.
Conventional server memory and solid-state drive demand offset uncertainty around high-bandwidth memory (HBM), the specialized component used in AI accelerators. Orders for server DDR5 memory are growing and extend into 2027, supported by continued deployment of new AI inference systems. Demand for Nvidia's (NASDAQ:NVDA) system-on-chip memory modules has also strengthened.
UBS estimates HBM shipments will rise 49 percent year-over-year in 2027 as manufacturers shift memory configurations to balance competing demand across product categories.
Analysts dismissed concerns about Chinese rival CXMT adopting more advanced DRAM technology as premature. They expect CXMT's near-term work to focus on research and sample production rather than significant capacity increases.
UBS flagged the possibility of accelerated capacity expansion by Samsung, potentially exceeding 150,000 wafer starts per month of DRAM capacity in 2028. But analysts view such expansion as unlikely to materially alter industry supply-demand dynamics before late 2028.
The recent correction should prompt memory makers to increase shareholder returns, providing additional support for sector valuations.
