In October 2008, as a hedge against inflation, I purchased a 5 year, $25,000 Treasure Inflation-Protected Security (TIPS) at a discounted price of 89.114 with an interest rate of .625%. As of last October 2009, its inflation-adjusted value was $25,497.25. So in 12 months, it has increased in value by $3,188.75 [25,000 - 22,278.50 (25,000 x .89114)] but most due to the discount. I only bought one because they were new to me as an investment vehicle but I thought that the best way to test out the waters is to get your feet wet.
