US TIP Bonds (TIPS)

Problem with inflation-indexed bonds is that when inflation is expected to go up, they can perform really well if inflation does actually go up. But if the market anticipates inflation rising, and it doesn't, these bonds perform horribly. 

The average investor shouldn't touch them. Leave them to the professionals.

This holds US inflation-protected bonds. Maybe USD will outperform CAD. This could be a good diversifyer if you already own Canadian bonds (ETF).
