First why don't you trust it, mutual funds spread over a wide set of funds.
have your money split between 8 good funds, each diversivied.
Also you can have your 401 invest in gold and other investments with the right fund.
But considering I am still making over 12 percent and had been doing 16 for the past 2 years with my worst mutual fund doing 8 percent, I have no idea why you don't trust it.
But if you want to put it in a safe, you can move it over to an insurance company like Met or Woodsmen that that gives you a guarntee of 3 percent on your IRA or 401K investment
If you cash them out you wll pay penalties, but they can be transfered to another protected fund.
gold has alot of risks, and while its past 10 years looks good, its 20 year is not that good it is first back to where it was in the early 80s
