💡 Investment Points Summary
- AI, Spillover Effects to Hardware 본격화 (Full-fledged): As AI model competition intensifies, the performance improvement of AI server, data center, and related semiconductor companies supporting them becomes more pronounced. An investment strategy of increasing the proportion of AI infrastructure-related stocks in portfolios seems effective.
- Biotech Sector, Entering a 'Distinguishing the Wheat from the Chaff' Phase: Like Moderna's success story, capital is flowing to companies with clear clinical data and technological capabilities. It is advisable to meticulously analyze specific pipelines and clinical trial progress rather than relying on mere expectations.
- Continued Rotation within Leading Stocks: While major market-leading themes (AI, Biotech) persist, a rotational market continues, driven by profit-taking from short-term surges and the search for new beneficiaries. Approaching with a strategy of staggered buying during corrections, rather than chasing rallies, is advisable.
