Dollars and Sense
The fund is designed to gradually reinvest your money each year into less risky investments to protect your money as you get closer to needing it. That way, if there is a severe downturn, the value of your nest egg will not change dramatically. Most, if not all, of the major fund families offer such a product.
With this type of account, invest as much as you can each month and don’t worry about what is happening to the stock market. Don’t even look at the balance of your accounts. Just keep saving month after month and trust that your investments will grow by the target date.
