SK hynix is a leading memory semiconductor stock in the AI cycle. As memory demand rises with token usage, SK hynix benefits directly from HBM and DRAM. The company has strong earnings momentum, and the current valuation is still attractive relative to growth prospects.

Samsung Electronics is a core memory semiconductor beneficiary in the AI cycle. Its earnings have grown faster than its stock price, compressing the P/E ratio from 15x to 6x despite the price doubling, indicating it remains cheap relative to earnings growth. The strong earnings base and continued upward revisions support further upside.

KOSPI fell excessively because panic, leverage, and fund liquidations pushed volatility to abnormal levels. If Samsung Electronics and SK Hynix earnings estimates do not break, the market is now undervalued and foreign investors have a base to buy again as volatility normalizes.

NVIDIA is the primary direct beneficiary of the AI cycle. For Korean investors who can buy US stocks, it is better to buy the core beneficiary (NVIDIA) directly rather than Korean supplier stocks, as it offers the most direct exposure and likely better returns.

Humanoid robot hardware is already commoditizing, so real-world factory data is the key differentiator. Hyundai Motor has an edge because it can mass-produce and deploy Atlas robots in its own factories, while Hyundai Mobis is the actuator play for that robotics path. Investor Day disappointment is short-term and does not derail the medium-to-long-term robotics story.

Construction is the intersection of nuclear power, AI data centers, and semiconductor fab capex. Unlike apartment and real estate construction, these projects are less cyclical and must be built over the next two to three years.

US power shortages, gas turbine and generator supply-chain delays, and Westinghouse IPO and stake-involvement catalysts are accelerating large nuclear orders, SMRs, and related power infrastructure.

Moderna's Phase 3 success for a personalized cancer vaccine validates gene-analysis-based drug development. That should expand the gene analysis market, and AI further accelerates biotech drug development. US biotech is acting as a defensive winner while tech rests, with many gene analysis names at new highs.

US neocloud companies Nebius and CoreWeave are already monetizing AI compute infrastructure, showing very strong earnings, with Nebius up 34% after results and CoreWeave's neocloud earnings confirming demand. The market is tight enough that short-term contracts are priced much higher. She says US stock investors can buy these directly instead of chasing early-stage domestic AI cloud proxies.

Naver has started losing search leadership to Google, and the rise of AI agents/crawlers means machines may increasingly consume web content instead of human users. Google has its own Gemini model and is better positioned for AI-driven search, while Naver lacks a proprietary AI model and is only beginning to build its AI/cloud business, so Google is preferred and Naver faces structural risk.
