NEW YORK ( ETF Expert) -- Eighteen months ago, Jim Rogers explained that "everybody is having a wonderful time running the printing presses." His answer? Protect yourself by owning real assets.In fact, the popular investing guru has publicly denounced equities for years while simultaneously expressing a preference for precious metals and agricultural commodities. Whenever you listen to Rogers, you may find yourself agreeing with his assessment of world disorder. On the other hand, PowerShares DB Precious Metals ( DBP), PowerShares DB Agriculture ( DBA) as well as the Rogers International Commodity Index Total Return ( RJI) have failed to provide the kind of results that broad-based U.S. stocks have.
