iShares MSCI Brazil Capped ETF (NYSEArca: EWZ)
Odds: 3/1
YTD: Down 20.3%
Comment: The ETF for the host nation is to this point in 2013, the worst on this list and in a bear market to boot. Brazil’s recent third-quarter GDP report showed contraction for the first time since 2009. Compounding Brazil’s woes is the fact that emerging markets such as China, India and Mexico saw growth rebound in the third quarter.
