Laddering

Laddering is an investment strategy that calls for establishing a pattern of rolling maturity dates for a portfolio of fixed-income investments. Your portfolio might include intermediate-term bonds or certificates of deposit (CDs).

For example, instead of buying one $15,000 CD with a three-year term, you buy three $5,000 CDs maturing one year apart. As each CD comes due, you can reinvest the principal to extend the pattern.

Or you could use the money for a preplanned purchase, have it available to take advantage of a new investment opportunity, or use it to cover unexpected expenses.

You can use laddering to pay for college expenses, with a series of zero coupon bonds coming due over four years, in time to pay tuition each year.

And if you ladder, you can avoid having to liquidate a large bond investment if you need just some of the money or to reinvest your entire principal at a time when interest rates may be low.
