SK Hynix ETFs now drive the stock's trading as AI memory mania peaks

ETF flows are becoming a bigger driver of SK Hynix trading than the actual memory chip fundamentals. The Korean giant's share price has surged 230 percent year-to-date on AI memory demand, pushing it into the $1 trillion market cap club, but iShares MSCI South Korea ETF now holds almost 30 percent of its $23.9 billion assets in SK Hynix alone. When a single-stock leveraged ETF tracking SK Hynix surged 50 percent on a day the underlying stock fell 8 percent due to liquidity issues in its market-making system, it confirmed the tail is now wagging the dog. Fund flows into memory-themed products like Roundhill Memory ETF, which dedicates 27 percent of its $11.6 billion to SK Hynix, are creating feedback loops that amplify every move in the underlying stock. AI infrastructure demand is real, but when ETF mechanics matter more than earnings, someone is overpaying.
