💡 Investment Points Summary
- AI's ultimate destination is 'power': Beyond AI semiconductors and software, 'power' related stocks (transformers, power cables, utilities), which are core infrastructure for driving AI, are emerging as new market leaders.
- Return of traditional energy strength: Inflation and geopolitical risks create a favorable environment for strong oil prices. It is necessary to pay attention to the earnings turnaround of refiners due to improved refining margins.
- Individual momentum in 'security' and 'bio': Separately from the market's macro trends, selective access to security stocks expected to benefit from government policies (Zero Trust) and biotech stocks with individual clinical success momentum remains valid.
