SK Hynix shares have plunged 41% this month, erasing hundreds of billions in market value ahead of the company’s Q2 2026 earnings report scheduled for July 29. The South Korean memory chipmaker’s stock collapsed from record highs reached during its Nasdaq debut on July 10, when shares surged 14% in the biggest-ever U.S. listing by a foreign company, to current lows reflecting mounting investor concerns about the sustainability of the artificial intelligence-driven chip boom.
The sharpest damage came on July 13, when SK Hynix shares fell more than 15% in a single trading session—the stock’s worst-ever one-day decline—wiping out more than $26 billion in market capitalization, according to Yahoo Finance. The collapse triggered a broader semiconductor selloff that extended across the sector, with the Philadelphia Semiconductor Index dropping 4.8% in a single week.
The selloff reflects investor anxiety about AI infrastructure spending growth, the core driver of SK Hynix’s extraordinary 2026 performance. Analysts at Motley Fool and ThemesETFs flagged concerns over a potential slowdown in artificial intelligence capital expenditure, the primary source of demand for high-bandwidth memory chips that SK Hynix specializes in producing. The company had benefited from a $750 billion surge in planned AI investments across 2026, but uncertainty about the pace of future spending has rattled confidence in memory chip valuations.
Despite the month-long decline, analysts remain optimistic about SK Hynix’s near-term earnings. According to Markets.com, analysts expect SK Hynix to post an operating margin of 75–77% in Q2 2026, marking the third consecutive quarter of record profitability. Minsook Chae, an analyst cited by Binance, forecasted SK Hynix’s operating profit in Q2 2026 to reach 60.4 trillion won, representing a 61% quarter-on-quarter increase and a 556% year-on-year surge. S&P Global reported that analysts expect Q2 revenue to rise 260% year-on-year to $52 billion, with DRAM generating $40.4 billion.
SK Hynix’s dramatic volatility—from the euphoria of its U.S. debut to sharp losses—mirrors broader uncertainty in semiconductor valuations after a record-breaking first half of 2026. The company’s shares had nearly doubled earlier in the year, but the recent correction has prompted investors to reassess whether AI spending growth can sustain the sector’s lofty multiples. SK Hynix’s record Q2 earnings are expected to demonstrate the company’s continued strength in meeting AI memory demand, though the market’s reception will likely depend on management guidance for the remainder of 2026 and 2027.
The sell-off also coincides with a broader reassessment of memory chip stocks. Samsung and SK Hynix leveraged ETFs have suffered steep losses, with retail investors who bet heavily on the AI memory trade facing significant drawdowns. The Roundhill Memory ETF slipped into bear-market territory, down 23% from recent peaks, reflecting the sector-wide pressure.
