My company contributes 10% (based on my salary) into a 401k, no matter what I put in. Next year, I will be 100% vested. Other than the growth numbers they provide, I don't really know much about the various funds they allow me to move my money between. At the moment, I'm just playing around with about 30% of the value in funds labeled something other than 'stable'

. Can someone give me some opinions about my options here?
