The Market Beta of a given security dictates it's historical
performance relative to a given market index.  For example, Google's
stock's market beta is Given by
Covariance(Goog,Nasdaq)/Variance(Nasdaq) where Goog and Nasdaq are
historical rates of return from Google IPO to present.

Considering the "Market" in this case to be the S&P500 Index, what is
the Beta of the following indexes:

1.  FTSE CHINA/XINHUA 25 Index (XFI)
2.  MSCI AC Asia-Pacific Ex-Japan Index
3.  MSCI All World Emerging Markets (EEM)
4.  FTSE All World BRIC Index
5.  Dow Jones China CBN Retail Index (DJCBNRTL)

Much of the information needed should be on Yahoo!Finance and Google Finance.

Again, what are these individual Market Betas with respect to the S&P500?
Thank you very much and best of luck solving.
