This ETF offers broad-based exposure to TIPS, bonds issued by the U.S. government featuring principal that adjusts based on certain measures of inflation. As such, TIPZ may have appeal as a minor allocation in a long-term portfolio, with increased weighting given if investors are particularly concerned about inflationary pressures. TIP is one of several broad TIPS ETFs; and it is arguably the second most popular of the bunch, right behind TIP in terms of assets under management in the Category. This fund is competitive from a cost perspective and offers up impressive liquidity, making it worthy of consideration for any investors seeking exposure to this corner of the bond market. While TIPS have become popular as a means of protecting against inflation, it is noted that there are potential limitations to this asset class in accomplishing this objective as well. Short-term TIPS ETFs such as STIP or STPZ may be forth a closer look, as well as more creative alternatives such as CPI or other 'alternative' ETFs.
