Brazil has emerged from the global economic crisis with a stronger financial system and a positive outlook, and the iShares MSCI Brazil Index ( EWZ) has responded by rising more than 42% year to date.While much of Brazil's, and EWZ's, success will depend on the continuing recovery of the commodity markets, the country's fundamentals will undoubtedly help support a continued upswing. Brazil's current administration has taken formidable steps to renew the country's financial system, and countries around the globe are eager to invest in this commodities-rich nation. Exchange-traded funds are an excellent way to gain exposure to Brazil, and the ETF industry has responded to the nation's potential with a number of Brazil-themed products. With a three-month average daily trading volume of more than 21 million shares, EWZ dominates the group, but a recent offering from Van Eck ETF group Market Vectors, the Brazil Small-Cap ETF ( BRF), has already attracted ample investor interest. For sophisticated investors interested in currency trading, Wisdom Tree offers the Dreyfus Brazilian Real Fund ( BZF). The three ETFs mentioned are very different in their construction.
