Q. I’m 27 and contribute 5 percent of my income to the Thrift Savings Plan, which I have in the C and I funds. I’m considering opening a Roth IRA, as well as investing in an aggressive growth mutual fund. Would I be better off just increasing my TSP contributions?
A. If you insist on long-shot betting — making bets that are more likely to lose than to win — you’ll have to go outside TSP. If you want an aggressive investment that maximizes your risk-adjusted expected returns, try the TSP’s S Fund.
