iShares MSCI Netherlands ETF (NYSEArca: EWN)

YTD gain: 24.3%

AUM: $302.9 million.

Comment: As the returns indicate, EWN has delivered an impressive 2013 performance, but how the ETF finishes the year will be an interesting scenario to watch. Interesting because on the last trading day of November, Standard & Poor’s ratings firm trimmed the Netherlands’ credit to AA+ from AAA due to “less promising” economic prospects and slower growth than other European countries, Financial Times reports.
