The iShares MSCI All Peru Capped ETF (NYSEArca:EPU) will give investors exposure to a high-growth South American country that has a heavy reliance on commodity prices. The broad array of single-country ETFs now on the market make this challenge easy to meet for investors looking to buy on the dip in rapidly expanding countries such as India. This move is in response to rising commodity prices, which has led to fears of inflation in the booming nation, which surpassed Japan last year as the world's second-biggest economy.
