Samsung Electronics and SK Hynix are direct beneficiaries of the AI investment boom. The intense competition among frontier AI labs (e.g., OpenAI, Anthropic, Google DeepMind) drives continuous demand for HBM and other semiconductor components, requiring more data centers and advanced chips. These two companies dominate Korean semiconductor production and have the competitive edge to capture this demand growth for years.

The KOSPI rally is not at its peak because while Samsung Electronics and SK Hynix dominate earnings and exports, the rest of the market is also recovering. Non-semiconductor exports have reached a new high, and other companies' operating profits grew 45% year-on-year. Historical patterns from the dot-com bubble show that such concentration can last over a year before a top forms, and current fundamental data supports a continued broad recovery.

NVIDIA, BlackRock, KKR and other large players are building a chip/GPU-based computing-finance and securitization structure to pull third-party money into AI infrastructure. Kim likens this to a compressed MBS-style boom-bust; while he warns about long-term bubble risk, he believes the new funding channel lowers AI capital costs and will bring substantial money into AI and NVIDIA-related infrastructure in the near term.

Microsoft has the strongest cash position among hyperscalers with the lowest capex-to-operating cash flow ratio (57%), giving it the greatest financial headroom to increase AI investment without straining free cash flow. It is also the most transparent in disclosing capex composition, especially short-lived assets like GPUs. The upcoming earnings report is expected to show continued investment growth, which should be a positive catalyst for the stock, especially after recent underperformance.

Gold's rebound reflects ongoing diversification away from US Treasuries because even long-term Treasury ETFs suffered extreme drawdowns and trust in US government bonds has been damaged; the Bank of Korea and other central banks are buying gold, and gold has risen even as Treasury yields rose, confirming this safe-haven rotation.

Within the M7/hyperscaler group, AI capex is causing differentiation: Meta is spending about $1.1 on capex for every $1 earned and looks burdensome, Amazon's cash position raises questions, while Microsoft and Google appear relatively more balanced; investors should now disaggregate the group rather than treat it as one trade.

Kim views the Nvidia/BlackRock/KKR/Brookfield AI infrastructure financing as a chip-backed securitization similar to MBS. It shifts GPU and datacenter-related debt and risk to pension funds and sovereign wealth funds, easing circular-financing concerns, while datacenter demand provides relatively steady yields. He rates the news as more important than the market did and expects it to pull institutional money into AI infrastructure near term.

Kim says US 10-year and 30-year Treasury yields have kept rising regardless of Fed rate freezes and oil-price declines, reflecting fiscal sustainability and sticky-inflation concerns. He sees no special measure that will bring long-term yields down sharply; if the Fed resumed buying Treasuries, long-term yields could rise even more because liquidity would loosen and inflation would stay harder to control. Yields will keep intermittently hurting risk assets until the base rate is actually raised.

Kim argues that the post-pandemic abundant-liquidity era is ending as long-term rates rise in the US, Japan and Europe. Rather than selling everything, investors rotate into the most reliable 'ace' assets, and he expects global funds to concentrate even more into AI in the near term, even if this becomes a bubble.

Rate hike expectations will intensify as Wall Street and Washington reassess the policy path. Recent US Treasury yield rises are not fully reversing on positive news, indicating that the market is beginning to price in a genuine shift toward rate hikes. As more economists and officials acknowledge the need to combat inflation and reduce inequality via rate hikes, yields are likely to continue climbing, making US Treasuries unattractive.
