The Chinese Yuan is pegged to the US Dollar --- with occasional 'adjustements' or small revisions by the Chinese government.   This chart shows a general, vague idea of what 'may' be the movement of the currency if it were allowed to float.   Both the Australian Dollar (developed market) and the Brazilian Real (emerging market) are considered 'commodity currencies' and are in a way comparable to China.

Options market makers use daily volatility as their measure of how to handle securities with different sensitivities to broad events and market moves.   Getting a basic understanding of volatility can be quite useful when thinking about how to weight your holdings.    If you expect high returns, then high volatility is fine  --  you are expecting to be paid for the risk.   A major problem would be owning securities that are very volatile but you do not expect them to offer high returns.  

The Emerging Markets Index (EEM) has been more volatile from a daily standard deviation perspective every month for the last few years.   There has been no change in this in 2010.    Looking at the returns by month as in the first chart shows how this YTD period is hardly an unexpected outcome.
