The S&P 500 gained 2.3% this week and investors took some bad economic data in stride, including a wider trade deficit and lower consumer confidence numbers. The focus may shift to Asia next week with President Obama visiting China. Expect lots of attention on currency, commodities and trade. Although they didn't do well enough to merit a spot as the weekly winners, both iShares FTSE/Xinhua China 25 ( FXI) and Claymore/AlphaShares China Small Cap ( HAO) closed at new 52-week highs this week. Here are the past week's winners and losers.
