SK Hynix’s extraordinary earnings and long-term memory contracts are restoring confidence in the AI investment cycle. Yet significant differences in country ETF performance and capital flows suggest the next phase of international leadership will be more selective than the previous semiconductor rally.
Korea’s Earnings Surprise Changes the AI Narrative
South Korea’s equity market surged 6.6% Wednesday following extraordinary earnings from SK Hynix, providing some of the strongest evidence yet that AI infrastructure investment continues generating substantial economic returns. The company reported quarterly revenue of KRW 104.6 trillion, up 328% year over year, and operating profit of KRW 83.3 trillion. More importantly, management disclosed long-term supply agreements with 14 major customers covering more than 50% of planned production capacity for 2027 and 2028, while projecting memory demand will exceed supply through 2030.
These announcements directly challenge concerns that AI infrastructure demand is approaching a cyclical peak. Unlike speculative developers financing future computing capacity, SK Hynix is generating exceptional profitability today, with substantial demand already committed through multiyear contracts. Its approximately $75 billion shareholder-return program further highlights the financial strength of the industry leaders, although part of that distribution reflects nonrecurring gains from its Kioxia investment.
The broader Korean economy is benefiting. Third-quarter GDP expanded 1.0% sequentially and 3.4% annually, supported by semiconductor exports and investment. However, weak domestic consumption and persistent energy inflation mean the recovery remains concentrated rather than broadly distributed.
The implication is that the AI investment cycle is fundamentally stronger than recent equity-market sentiment has suggested—but its benefits remain concentrated in a relatively small group of companies and industries.
Country ETF Performance Reveals a More Complicated Rotation
The latest country ETF data show investors increasingly willing to accumulate semiconductor exposure following the recent correction, while differentiating sharply among other international opportunities.
| Country / ETF | 1M return | 1M net flows |
| South Korea (EWY) | -15.88% | +$458M |
| Taiwan (EWT) | -6.56% | — |
| Japan (EWJ) | -2.74% | +$952M |
| China (MCHI) | -6.73% | -$156M |
| India (INDA) | -2.34% | -$134M |
| Switzerland (EWL) | +4.52% | +$122M |
| Canada (EWC) | +2.45% | +$247M |
| Italy (EWI) | -7.52% | +$144M |
| Spain (EWP) | -5.72% | -$309M |
| Brazil (EWZ) | -6.84% | +$3,930M |

Korea’s positive $458 million in monthly ETF inflows despite a 15.88% decline suggests investors have been accumulating during the correction. Year-to-date inflows of $8.20 billion reinforce the scale of investor commitment. However, the sharp drawdown shows that strong earnings have not eliminated valuation and positioning risks.
Taiwan offers a useful comparison. EWT has declined 6.56% over the past month but remains up 22.78% over six months, versus just 0.47% for Korea. TSMC’s recent 50.9% year-over-year revenue growth and strong foundry margins provide an independent confirmation of AI demand. Taiwan’s more resilient relative trend favors maintaining core exposure there while selectively rebuilding Korean positions.
Japan represents a different opportunity. EWJ attracted $952 million despite a 2.74% monthly decline, reflecting continued demand for industrial automation, advanced manufacturing, and corporate reform. Unlike Korea’s concentrated memory exposure, Japan offers more diversified earnings drivers, although rising domestic interest rates remain a risk.
Memory Demand Could Broaden AI Leadership
The SK Hynix announcements also reveal an important distinction within the semiconductor trade. Rising demand for high-bandwidth memory is not dependent exclusively on Nvidia’s continued dominance.
Reports that OpenAI plans to purchase Google’s custom TPU processors suggest AI developers are diversifying their hardware architectures. Both GPUs and advanced TPUs require high-bandwidth memory, potentially broadening the opportunity for memory suppliers even as competition intensifies among processor designers.
China’s CXMT is reportedly preparing to manufacture HBM3E chips, but production yields of approximately 20%–30%, compared with roughly 70% for SK Hynix, illustrate the considerable technological gap that remains. Chinese competition is a longer-term concern rather than compelling evidence of an imminent collapse in Korean pricing power.
For U.S. sector investors, the read-through supports selective Technology exposure through VGT and semiconductor suppliers including Nvidia (NVDA), Micron (MU), and TSMC (TSM). Industrials benefiting from electrical infrastructure and automation, including Eaton (ETN) and Quanta Services (PWR), also retain attractive demand drivers. However, increasing memory prices create potential margin pressure for consumer electronics manufacturers, reinforcing the importance of distinguishing suppliers from downstream customers.
Outside Asia, Investors Are Becoming More Discriminating
European flows reveal a similar distinction between accumulating quality and attempting to catch falling markets. Switzerland has attracted $122 million alongside positive monthly performance, while Italy received $144 million despite a 7.52% decline. Spain, by contrast, experienced $309 million in withdrawals during its 5.72% drawdown. Elevated sovereign borrowing costs and inflation continue undermining the broader European recovery thesis.
Canada’s positive returns and inflows reflect the appeal of resource and financial exposure amid elevated energy prices. Norway also remains well positioned as an energy exporter. Australia’s September inflation acceleration to 4.3% underscores why monetary policy and commodity prices remain important cross-country differentiators.
Brazil illustrates the dangers of extrapolating backward-looking flows. Despite $3.93 billion of rolling monthly inflows, EWZ declined 19.31% during the latest week, accompanied by $135 million in withdrawals following the October 25 election. Political and fiscal uncertainty have substantially changed the near-term investment environment.
China and India continue experiencing withdrawals alongside negative performance. China’s improving semiconductor capabilities have yet to overcome weak domestic demand, while India’s imported energy costs and elevated financing pressures remain obstacles.
Investment Conclusion: Favor AI Earnings Visibility With Broader Diversification
Our preferred international accumulation candidates are Taiwan (EWT), Japan (EWJ), South Korea (EWY), Switzerland (EWL), and Canada (EWC). Taiwan offers established semiconductor manufacturing leadership; Japan provides diversified industrial growth; and Korea now offers a potentially attractive recovery opportunity supported by unusually strong memory earnings and contractual demand visibility. We would accumulate Korea gradually following its sharp rebound rather than chase momentum indiscriminately.
Switzerland provides defensive earnings exposure, while Canada offers financial and commodity diversification. Norway (ENOR) remains attractive tactically as an energy hedge. Italy (EWI) warrants monitoring for mean reversion, but we remain cautious toward Spain (EWP), China (MCHI), India (INDA), and Brazil (EWZ) until financing, earnings, or political uncertainty diminishes.
The next decisive test comes from Microsoft and Alphabet earnings Wednesday evening, followed by Amazon Thursday. Continued cloud revenue acceleration and strong backlog conversion would reinforce Korea’s evidence of durable AI demand. Disappointing monetization or rising financing requirements would sustain pressure on valuations despite strong semiconductor results.
South Korea’s earnings demonstrate that the AI investment cycle remains powerful. The investment opportunity is increasingly about selecting countries and sectors where that growth is already producing profits—rather than merely financing the promise of future demand.
