Inflation-Proofing Your Portfolio  Like other debt instruments with relatively long periods to maturity, the market prices of TIPS Notes and Bonds fluctuate daily due to interest rate changes and other economic factors. However, interest rate changes that are due solely to expectations about future inflation rates should not drastically affect the market prices of TIPS instruments. (Daily prices and yields on all U.S. Treasury debt securities, including TIPS, can be found in The Wall Street Journal and other sources.)
