We all must account for inflation in our daily operations. Inflation never goes away, so we may as well make it part of the family.
Investing in Series "I" Bonds and Treasury Inflation-Protected Securities (TIPS) are two ways to beat inflation.
They each have their advantages and disadvantages, but you must understand how they can fit into your investing profile.
These securities are only part of your overall portfolio management and can help you achieve your goals with little risk to the principal. Good Luck!
