I'm looking at the Vanguard Canadian Aggregate Bond Index ETF (VAB), and it says it replicates the "Barclays Capital Global Aggregate Canadian Float Adjusted Bond Index". Unfortunately VAB is less than a year old, so to understand the historical performance and volatility I have to look directly at the index that it is based on.
On Barclays's official site (renamed from Lehman), the index seems to be called "Global Aggregate Float Adjusted CAD". The only data I can find is its 1 year performance here: https://ecommerce.barcap.com/indices/index.dxml. In particular, I can't find information on historic year-by-year returns or the composition of the index.
I have searched sites such as Bloomberg, Google Finance, and Google and found no useful results. Where can I learn more about this Barclays Aggregate Canadian Bond Index? Also, are there other, older funds based on this index?
