SK Hynix Faces AI Spending Scrutiny After Sharp Correction
SK Hynix Inc. ($000660 KS) shares declined by 6.7% to ₩178,000 on May 24, marking its steepest single-day drop since October 2023, as investors reassessed the aggressive valuations in the artificial intelligence semiconductor sector. The memory chipmaker, a crucial supplier of High Bandwidth Memory (HBM) for AI accelerators, has seen its stock retreat 18.5% from its May 13 peak of ₩205,500.
This downturn reflected growing anxieties regarding the long-term sustainability of AI capital expenditure and potential oversupply risks in advanced memory, following a period of meteoric gains driven by the AI boom. While still up over 30% year-to-date, the recent correction signals a shift in market sentiment towards greater scrutiny of AI-related revenue streams and margins.
Market Impact
The recent correction saw SK Hynix's market capitalization drop by approximately ₩18.7 trillion ($13.6 billion) from its May 13 high, settling around ₩129 trillion ($94 billion) by late May. This move represented a significant reversal for a stock that had surged nearly 100% over the past twelve months, outperforming the broader Kospi index by a substantial margin. The May 24 decline was accompanied by trading volumes exceeding 14 million shares, significantly higher than its 30-day average of 9 million shares, indicating strong selling pressure.
Historically, SK Hynix has experienced periods of sharp volatility, particularly during semiconductor cycle downturns. The current correction, however, comes amid robust demand for its HBM products, highlighting investor sensitivity to any potential deceleration in AI infrastructure spending. This volatility has spilled over to other memory manufacturers, with Samsung Electronics Co. ($005930 KS) also seeing a 2.5% drop in its shares on May 24, while U.S.-listed peers like Micron Technology Inc. ($MU) faced similar pressures, declining 3.1% on the same day. The broader Philadelphia Semiconductor Index ($SOX) also dipped 2.8%, underscoring a sector-wide re-evaluation.
What Analysts Are Saying
Analysts offer mixed views on SK Hynix's immediate trajectory, balancing robust HBM demand against potential short-term market corrections. According to a research note from Morgan Stanley on May 27, "SK Hynix remains uniquely positioned in the HBM market, particularly with its HBM3e and upcoming HBM4 offerings, which are critical for next-generation AI accelerators. While short-term profit-taking is natural after such a strong run, the structural demand for AI memory is far from peaking, justifying a long-term bullish outlook with a price target of ₩240,000." The firm highlighted SK Hynix's leading market share in HBM, estimated at over 50%.
Conversely, JPMorgan Chase & Co. analysts, in a client briefing on May 23, expressed caution. They noted, "The significant ramp-up in HBM capacity across multiple vendors could lead to pricing pressure in 2025, even with strong AI demand. Furthermore, the concentration of AI capital expenditure among a few hyperscale cloud providers introduces customer-specific risk. We maintain a neutral rating on SK Hynix, suggesting that current valuations may not fully account for these potential headwinds, with a downside risk to ₩165,000." This perspective emphasizes the supply-side dynamics and customer concentration.
A more balanced view from Goldman Sachs on May 26 acknowledged the recent correction as a "healthy consolidation." They stated, "The AI narrative remains intact, but investors are becoming more discerning. SK Hynix's exposure to Nvidia's ($NVDA) HBM supply chain is a clear strength, yet any signs of slowing capex from major cloud providers or competitive pressures could trigger further volatility. We foresee a period of consolidation before the next leg up, advising investors to monitor HBM average selling prices (ASPs) closely."
What to Watch
Investors should closely monitor several key catalysts and data points to gauge SK Hynix's rebound potential. The company's upcoming second-quarter earnings report, typically released in late July, will provide crucial insights into HBM sales, average selling prices, and forward guidance. Any revision to capital expenditure plans by major AI infrastructure players like Microsoft ($MSFT), Amazon ($AMZN), and Google ($GOOGL) will directly impact HBM demand forecasts.
Key technical levels for $000660 KS include the support at ₩170,000, which if breached, could signal further downside towards ₩160,000. Resistance is currently observed around ₩190,000, with a clear break above ₩200,000 needed to confirm renewed bullish momentum. Furthermore, the ramp-up of HBM3e production and the successful qualification of next-generation HBM4 with key customers will be critical for maintaining SK Hynix's competitive edge and pricing power into 2025.
Risk factors that could reverse any rebound include a broader economic slowdown impacting enterprise IT spending, increased competition in the HBM market from rivals, and potential geopolitical tensions affecting semiconductor supply chains. The quarterly earnings calls of major AI chip developers, such as Nvidia's next report in August, will also be pivotal for understanding the broader AI hardware demand landscape.
