Company sponsered 401k’s can be a crap shoot if their investment offerings are limited.

I’m a conversative investor. I manage a self-employed 401k for myself and alot of my money is in US market index funds (e.g. s&p 500, wilshire 5000). Frankly, my US index funds have gotten battered this year. I’ve done much better in my non-us index type funds (SE asia and worldwide). You’ll have to weigh your options with your employer and see what you can find that is worthwhile.

Frankly, employer sponsered 401k’s these days suck. With 3-5 year vesting periods (who works for their employers that long in this market) you’ll end up forfeiting much of their match in most cases.
