Highlights of VTIP: Seeks to track an index that measures the performance of inflation-protected public obligations of the U.S. Treasury that have a remaining maturity of less than five years. With interest rates on the move, investors can counter with Treasury inflation-protected securities (TIPS) or, more specifically, the Vanguard Short-Term Inflation-Protected Securities Index Fund ETF Shares (VTIP). If rates are going to rise on the short-term horizon, bonds can be susceptible to interest rate risk, but a fund like VTIP can help shorten duration.
