Once your emergency fund is set and you're capturing your 401(k) match, the next question is investing the rest. For most people the honest answer is delightfully boring: low-cost index funds.
Why index funds win
- One fund buys a slice of hundreds or thousands of companies — instant diversification
- Most professional stock-pickers fail to beat a simple index over time
- Target expense ratios under 0.10%; automate and ignore the noise
What an index fund actually is
Instead of betting on individual companies, an index fund buys a tiny slice of hundreds or thousands at once — for example, the 500 largest US companies. You get instant diversification, near-zero fees, and the long-run growth of the whole market. Decades of data show most professional stock-pickers fail to beat a simple index fund — you don't need to be smarter than them, you need to not pay them.
Open a brokerage account
Any major US brokerage will do. Look for no account minimum, commission-free trades, and access to low-expense-ratio index funds or ETFs. Expense ratios under 0.10% are the goal.
The NRI-specific trap — PFICs
- Do not hold Indian mutual funds while you're a US tax resident — the IRS classifies them as PFICs
- PFIC tax treatment is punishing and paperwork-heavy (Form 8621 per fund, every year)
- The fix: invest through US-domiciled funds while you're in the US, keeping India and US investments cleanly separated

Key takeaways
- A total US stock market index fund as your core
- A total international index fund for global exposure
- A bond index fund if you want to dial down volatility
Automate a monthly contribution, ignore the daily noise, and let compounding work over decades. Simplicity isn't a compromise here — it's the strategy.
