Is investing in an ETF generally your best option after establishing a Roth IRA?
When investing small amounts, you should consider the substantial toll that commissions will take on your investment. In your case, $800 placed in just one ETF will incur commissions of about $8 each way, or a total of 2% of your investment. I suggest you wait until you have at least $5000 to invest in stocks or ETFs. Since this is in a IRA, your options are limited, but perhaps you may qualify for a Vanguard mutual fund, which will not charge commissions and will have annual expenses only a trivial amount higher than the corresponding ETF. it should probably go in a mixed allocation fund, and since you are young, it should be a relatively aggressive one. Mutual funds will also allow you to contribute small amounts over time without incurring any extra fees.
