By looking at the advantages and disadvantages of these options, it was concluded that stock mutual funds might be a good place to put the money. An aggressive growth fund has the potential to do even better. They are easy to sell when you need the money, and can be sold at any time. You generally have to wait several days or a week to get your money out.
Mutual funds require thought.
With a savings bond you simply go down to the bank, buy the bond, put it in a drawer and forget about it. With a mutual fund you have to research and pick the fund, send in the money, and watch the fund to see how it performs. Before you invest money in a mutual fund, you have to decide if the potential benefit of an increased rate of return outweighs the disadvantages. The advanced rate of return can be important, but it is not guaranteed. That is a big difference.
