"The latest annual rate of inflation measured from last July to this July was 5.6%, the largest annual gain since way back in January 1991," observes Alexander Green.

Here, the investment director for the industry-leading The Oxford Club suggests that investors consider the iShares Lehman TIPS Bond Fund (ASE: TIP), noting, "This is a great way to buy a diversified portfolio of inflation-adjusted Treasuries and track them quite easily."

"The latest consumer price index figures were a bit of a shock; the annual rate of inflation measured from last July to this July was 5.6%, the largest annual gain since way back in January 1991.

"Despite these horrendous inflation figures, gold, mining shares and other inflation-sensitive indicators did nothing – or even fell. What gives?

"Remember that the market is always looking forward, not back. Investors are always more concerned with what lies ahead than what happened in the recent past. Next month or next year may be a different story entirely.

"That's why every investor should have a hedge in his portfolio, like inflation-adjusted Treasuries. These bonds are unique in the investment world. They are the only investment guaranteed to beat inflation. And they are great portfolio diversifiers. They don't march in step with either stocks or bonds.
