I haven't actually funded my Roth this year. The money is sitting in a savings account, waiting for me to figure out what to invest it in. Back in 2008 when I started saving for retirement, I spent a long time obsessing about what to invest in before finally settling on Vanguard Balanced Index (VBINX), which is about 60% total U.S. stock market and 40% total U.S. bond market. It wasn't a perfect choice; I could definitely use exposure to international markets, but I figured I should dive in with a not completely unreasonable choice and reassess later on.
I never quite got to the reassess part of the plan. Then the stock market tanked, and I got a lot more skittish about investing. I'd been telling myself that I believe in investing for the long term, buying and holding, and indexing, but I'm pretty risk adverse to begin with. (A 60% /40% portfolio isn't exactly what the blanket advice for people in their early twenties suggests, after all.) It was easiest to just quit thinking about it entirely. I have no idea how much I have in my Roth right now, and I'm going to keep telling myself it doesn't matter.
That doesn't really encourage thorough research into the options available. I really want to stick my head in the sand, throw $5,000 in a c.d. and be done with it, but that isn't a rational choice if I ever want to have enough to retire. What do you think, is sticking with VBINX for another year a reasonable default option, or should I try to find the time to do some more research?
