Buy, JJ, buy!

The yield on the five-year Treasury Inflation-Protected Security due in 2012 has been negative since Feb. 29, and traded today at minus 0.17 percent. The notes, which were first sold in 1997, have never before traded below zero. Even so, firms from Deutsche Asset Management to Vanguard Group Inc., the second- biggest U.S. mutual fund company, say TIPS are a bargain. Can't miss on that.
