SK Hynix stock fell approximately 37% over 18 trading days from a high near 3 million won in mid-last month, pushing individual investors toward losses. According to Naver Financial data on the 20th, the average purchase price for 295,591 SK Hynix investors was 1.811 million won, with an average return of just 1.71%. On the 16th, SK Hynix closed at 1.842 million won, down 11.53% from the previous trading day, placing most investors near break-even or loss territory. The sharp decline in SK Hynix and the broader semiconductor sector stems from emerging doubts about the sustainability of AI infrastructure investment, which has driven the memory semiconductor super cycle. AI data center and server memory demand had previously fueled historic earnings for domestic semiconductor companies, but recent developments — including New York State halting data center construction plans due to power shortages and rising electricity costs, and concerns that China's CXMT may expand production capacity after its IPO — have dampened investor sentiment.
US Semiconductor Stocks Decline on the 16th
On the 16th (local time), US semiconductor stocks fell broadly. SK Hynix ADR declined 13.69%, Micron fell 5.65%, SanDisk dropped 12.63%, Western Digital decreased 9.15%, and Nvidia fell 2.40%. The Philadelphia Semiconductor Index declined 4.29% in a single day.
Analysts Attribute Decline to Supply-Demand Instability
Securities firms analyze the recent weakness as stemming from temporary supply-demand instability rather than deteriorating fundamentals. The analysis notes that options trading, leveraged ETFs, trend-following funds, and increased quant and algorithmic trading amplify price movements mechanically. Once declines begin, hedge transactions and ETF rebalancing occur simultaneously, magnifying the drop. Some analysts view this correction as doubts originating from Big Tech — the primary AI infrastructure investors — transmitted and amplified in the domestic market. Given unstable trends in the S&P 500 and Nasdaq 100 volatility indices, analysts state it is difficult to predict direction prematurely. The prevailing forecast is that the market will remain more sensitive to negative news than positive until confirming US Big Tech earnings and capital expenditure guidance scheduled for late July.
