How to Size USD Dividend Allocation Against FX Risk

1. The "Dual" Nature of USD Dividend Stocks

Korean investors owning US stocks face dual risk: ① stock price, ② FX rate. Buying Realty Income at $60 with KRW/USD 1,300 costs ₩78,000. If FX drops to 1,100 next year with price unchanged, you lose 15% on FX alone.

2. FX as "Hidden Yield"

When FX rises, Korean holders get triple benefit: dividends + price + FX gains. This is why Korean investors must rebalance USD allocation through the FX cycle.

3. Strategy by FX Range

• 1,000-range (strong KRW): Aggressive USD buying. Grow to 40–50%.
• 1,100–1,250 (neutral): Mechanical DCA. Hold 30–40%.
• 1,300–1,400 (weak KRW): Slow new buys; keep positions. 25–35%.
• 1,450+ (extreme): Stop converting. Favor Korean / ISA. 20–25%.

4. Hedged vs Unhedged ETFs

Unhedged wins when FX rises; hedged wins when FX falls. Hedging costs 1–2% annually and erodes long-term returns.

5. FX Dollar-Cost Averaging

6. Converting USD Dividends Back

Two schools: Immediate convert (for living) vs Stay in USD (keep compounding). Long-term accumulators mostly win by staying USD.

7. Simulate in SO Dividend

8. Conclusion

FX is uncontrollable, but allocation is. Avoid both "all-in" and "none". Flex between 25–50% USD based on the cycle — that's Korean dividend survival strategy.
