Seen here:
In terms of owning inflation protected securities (TIPS), we find that at current price levels they offer absolutely NO protection against further increases in the US inflation rate. Rather, we believe that you should (at this point) own real assets such as commodities for protection or small cap stocks, which have proven to be a decent hedge against inflation historically.
Even after yesterday's pullback to $13.44, VIPSX is trading near ten year highs.
