For Conservative Investors

Positioning:

• Cash provides optionality
• Quality over growth

For Growth Investors

Positioning:

1. Buy US tech dips — Focus on GOOGL, AMZN, MSFT

3. Hold NVDA — Long-term AI thesis intact
4. Avoid TSLA — Weakness likely continues
5. Watch momentum — Don’t fight the trend

Rationale:

• Corrections are buying opportunities
• AI revolution just beginning
• Korean recovery has legs
• But manage risk carefully

For Korean Market Investors

Positioning:

1. Overweight semiconductors — SK Hynix top pick
2. Underweight autos — Hyundai lagging
3. Watch won closely — Hedging consideration
4. Monitor foreign flows — Key indicator

💡 BOTTOM LINE: WEEK IN REVIEW

What Worked

✅ Korean semiconductor stocks — SK Hynix +10.66%, Samsung +8.66% ✅ GOOGL & AMZN — Only Mag7 stocks positive ✅ KOSPI recovery — +4.17% outperformed globally ✅ Treasury stability — Yields contained

What Didn’t Work

❌ US tech broadly — Nasdaq -3.25%, correction underway ❌ Tesla — Worst Mag7 performer at -2.79% ❌ Momentum trades — High-multiple stocks hit hardest ❌ Risk-on sentiment — Rotation to defensive

The Big Picture

This week highlighted the importance of geographic diversification. While US markets struggled, Korean equities shone. The semiconductor sector was the common thread — Korean chipmakers surged while US chip stocks held up relatively better than software names.

The divergence suggests investors are rotating away from expensive US tech toward more reasonably valued international opportunities, particularly where there’s exposure to AI/memory chip demand.

Looking Ahead

Key Questions for Next Week:

1. Does US tech stabilize or accelerate lower?
2. Can Korean rally continue?
3. What does PCE inflation data show?
4. Will Fed officials signal anything new?

Our View: Maintain cautious optimism. The Korean recovery has fundamentals supporting it (memory price recovery, AI demand, foreign flows). US tech may need more time to digest valuations. Keep powder dry for opportunities.
