Japan now ranks first overall with a gain of 30.53%, but keep in mind that its currency has depreciated significantly this year. In dollar terms, Japan's stock market is up 14.04% YTD. This would still rank it 11th on the list, but it cuts the gains in half. In the G7, the US ranks second behind Japan, followed by the UK. After Japan, the US and the UK, the four other G7 countries are not doing very well. France is up just 0.30% on the year, while Italy, Germany and Canada are all down.
All four of the big BRIC (Brazil, Russia, India, China) emerging markets are down on the year as well. China is doing the best of the BRICs with a YTD decline of 1.19%. India is down 1.32%, while Brazil and Russia are now down double digit percentages. Brazil and Russia are both having very rough 2013s through mid-April.
