ETF IShares Global (IXC) (IOO)

I purchased two ETF's today. ETF's are Exchange Traded Funds and are basically like a mutual funds where they hold a basket of stocks but the expense ratio is much cheaper and the holdings typically don't change like a managed mutual fund. They are traded just like stocks. For example the IShares S&P Global Energy Index (IXC) which I bought today for $138.00 per share has a miniscule expense ratio of 0.48 percent. It holds energy companies and the top 10 holdings are Exxon, British Petroleum, Total, Chevron, Royal Dutch Shell, Schlumberger, ENI SPA, Occidental Petroleum , BG Group. . The other ETF I bought was IShares S&P Global 100 Index (IOO). Purchase price was $83.32 and the top 10 holdings are Exxon, GE, Citigroup, Microsoft, BP, HSBC, Total SA, Chevron, Proctor & Gamble, and Johnson & Johnson. This ETF holds the 100 largest Global companies.
ETF's are a great way to diversify, low expenses, and great liquidity.
