Another case for index funds

This time, it is slightly different.  It is the case for bond index funds.  Here is the snippet from the article Bond Indexes Beat Active Mutual-funds:

A study by Standard & Poor's found that on an asset-weighted basis -- measuring returns by the invested dollar rather than percentage of funds -- index returns beat actively-managed fund returns in all 13 fixed-income categories over one and three years, and in 11 of 13 categories over five year

For me personally, I follow FundAdvice.com recommendation and keep my fixed income securities in short term to intermediate term Treasury bonds and also in Treasury Inflation-Protected Securities (TIPS) as I am not looking at fixed income for growth, but as a way to reduce my portfolio risks.
