South Korea’s SK Hynix has filed to list American depositary receipts in the United States and could raise as much as $10 billion this year, a move that threatens to reshape investor flows in the global memory-chip sector and pile fresh pressure on US-listed rival Micron Technology.
Micron, the only major DRAM maker currently listed in New York, enjoyed a blistering start to the year — its shares jumped roughly 50 percent in January — but the stock has slipped sharply since a recent peak. Despite rallies last week and Monday amid broader market optimism tied to tentative diplomatic progress over the war in Iran, Micron remains nearly 20 percent below its high reached three weeks ago, and March marked its worst month in almost four years.
SK Hynix’s planned US offering, which if completed would rank among the largest New York debuts by a foreign firm, would give American retail and institutional investors a direct way to buy into a company that is closer to the front line of high-end memory used in artificial-intelligence systems. SK Hynix is a key supplier to Nvidia and captured 57 percent of global revenue for high-bandwidth memory (HBM) in the fourth quarter — more than double Micron’s share, according to Counterpoint Research.
Analysts say those facts could prompt a rotation of short-term capital. “You’ll see a rotation from quick money from Micron to SK Hynix because currently SK Hynix is trading at lower valuations,” said Rob Li, managing partner at the New York hedge fund Amont Partners. Kenny Kim, CEO of Seoul-based Meridian One Asset Management, added that the new listing would create fresh long-short opportunities for hedge funds because both stocks are memory “pure plays” while SK Hynix leads in HBM.
Valuation differences between the two companies are small but significant to traders. Both Micron and SK Hynix trade at about four times forward earnings, a steep discount to the S&P 500’s roughly 20-times multiple, but Micron still commands a modest premium. “The difference is likely because Micron is the one DRAM stock listed in the biggest equity market on the planet,” said Ted Mann, a global equities portfolio manager at Ariel Investments.
The potential inflow of SK Hynix ADRs could narrow that premium as US investors gain direct access to Asia’s larger DRAM producers. For Micron, the development complicates an already fragile momentum picture: investors are weighing cyclical memory-market dynamics, intense competition from Samsung and SK Hynix, and broader macro risks that have recently rattled markets.
What traders will watch next is whether SK Hynix’s ADR filing turns into a full-scale offering and how large US institutions and retail investors are in subscribing. A successful, sizable New York listing could redistribute capital across the memory sector at a time when demand from AI infrastructure and data-center builds remains central to chipmakers’ outlooks — and to how investors price the industry’s winners and laggards.
