If you want a diverse portfolio of solid companies, look no further than the Standard & Poor's 500 Stock Index. And you can buy a low cost mutual fund based on that index at either Vanguard.com or Fidelity.com (Don't let anyone sell you anything else.) Now, understand that over the long run this will be a good investment if America thrives and prospers. But the stock market always has ups and downs -- and those times can be scary. So you might want to put two-thirds of it into the mutual fund, and the other third into Treasury bills (see my recent column at my website) and that way you won't panic during a market drop.
