Hello, for preface, I am a Japanese citizen currently attending college in the states, and I’m exploring where I want to build my long-term career. At the moment, I invest in the S&P 500 through a NISA account with Rakuten Securities in Japan. Since I will soon begin part-time work in the U.S., I am also considering opening a Roth IRA and possibly a brokerage account with Fidelity. My goals are:
- To hold some assets directly in USD.
- To continue investing in the S&P 500 (at least within the Roth IRA).
However, I’m struggling with two concerns which conflicts with my goals:
- Diversification vs. growth: I understand diversification is important, but I worry that spreading out too much will reduce the long-term compounding power compared to focusing on the S&P 500 on a single nest.
- Account priority: Should I prioritize opening a Roth IRA (and potentially a Fidelity account) to invest directly in U.S. assets, or would it be better to convert my USD back to yen and continue concentrating investments through my existing NISA account?
Thanks!
