SK Hynix closed at 1,842,000 won on the 16th, marking an 11.53% decline and a 36.90% drop from its peak of 2,919,000 won recorded on the 22nd of last month. The decline stems from concerns over the sustainability of AI infrastructure investment, which has driven the memory semiconductor super cycle. The broader semiconductor sector experienced concurrent declines, with parent company SK Square falling 38.48% and Samsung Electronics dropping 27.86% during the same period, as questions emerged about data center construction plans and production capacity expansion by Chinese competitors.
Investor Losses Mount as Average Purchase Price Approaches Current Trading Level
According to Naver Financial, 295,591 SK Hynix investors hold an average purchase price of 1,811,094 won, resulting in an average return of just 1.71%. With the stock closing at 1,842,000 won on the 16th, a substantial number of investors entered loss territory. The 18-trading-day decline of approximately 37% concentrated profit-taking pressure on SK Hynix, which had experienced relatively rapid gains compared to Samsung Electronics' 27.86% drop during the same period.
AI Infrastructure Investment Concerns Trigger Semiconductor Sector Decline
The concurrent decline in SK Hynix and the semiconductor sector followed questions about the sustainability of AI infrastructure investment. New York state halted data center construction plans due to power and water resource shortages and electricity rate increases. Concerns emerged that China's CXMT could use funds secured through its IPO to significantly expand production capacity, potentially causing memory price declines. These developments rapidly contracted investment sentiment despite historical earnings driven by explosive demand for AI data center and server memory.
Analysts Attribute Weakness to Supply-Demand Factors Rather Than Fundamentals
Seo Sang-young, Managing Director at Mirae Asset Securities, stated that "options trading, leveraged ETFs, CTAs, and other trend-following funds, as well as quant and algorithmic trading, are mechanically amplifying price movements." He explained that "these funds adjust positions based on price momentum and volatility rather than corporate earnings, so once a decline begins, hedge transactions and ETF rebalancing simultaneously interlock to increase the magnitude of the fall." Seo added that "funds are rapidly moving to other relatively strong sectors, significantly shortening the inter-sector rotation cycle," and concluded that "the recent weakness is largely due to short-term supply concentrating in one direction using already known factors as a pretext, rather than the emergence of new negative news."
On the 16th (local time), US semiconductor stocks declined in unison. SK Hynix ADR fell 13.69%, alongside Micron (-5.65%), SanDisk (-12.63%), Western Digital (-9.15%), and NVIDIA (-2.40%), pushing the Philadelphia Semiconductor Index down 4.29% in a single day.
SK Hynix Q2 Earnings and Big Tech Guidance to Determine Stock Direction
Noh Dong-gil, Head of Investment Strategy at Shinhan Investment & Securities, stated that "the essence of this adjustment is a structure where doubts originating from the subjects of AI capital expenditure (Big Tech) were transmitted to the domestic market and amplified." He noted that "as the volatility indices of the S&P 500 and Nasdaq 100 show unstable trends, it is difficult to hastily predict directionality." Noh added that "until confirming the earnings announcements and capital expenditure guidance of US Big Tech companies scheduled for late July, the market will have to pass through a section that reacts more sensitively to negative news than positive news."
SK Hynix's Q2 operating profit consensus reaches 85 trillion won, though some institutions issued conservative reports that burdened the stock price. SK Hynix will announce Q2 earnings on the 29th. AI investment plans from major hyperscalers including Alphabet (Google), Amazon, and Microsoft, announced around the same period, will serve as important gauges for SK Hynix stock direction.
