With that said, let me introduce you to a company that is in the business of operating securities (i.e. stock) exchanges: NYSE Euronext ( NYX). At the moment, shares of NYX are "on sale!" Headquartered in New York City, NYX is an international exchange operator. It owns and runs the New York Stock Exchange (NYSE), NYSE Arca, Inc., and NYSE Amex LLC in the United States. It also operates five European-based exchanges comprised of the Euronext N.V., the Paris, Amsterdam, Brussels, and Lisbon stock exchanges, as well as the NYSE Liffe derivatives markets in London, Paris, Amsterdam, Brussels, and Lisbon.

You can learn more about the company by visiting its user-friendly Web site and exploring all the ways it makes money and makes markets for all sorts of investment products. NYX has a $6.22 billion market cap and an average daily volume of 2,385,000 shares traded. For various and sundry reasons, including the problems associated with Hurricane Sandy, NYX is trading closer to its 52-week low price. As I write, the share price is at $25.30, giving it a dividend yield-to-price of 4.74%. Try to find a company that has a solid corner on its market with a 22% operating margin, operating cash flow (trailing 12-month) of $938 million and levered free cash flow of $696 million with a dividend yield of 4.74%. Bet you can't! As you can see from the five-year chart below, there appears to be a disconnect between the share price of NYX and its impressive operating margin. My thesis is that this may be corrected in the very near future. NYX data by YCharts Now before you buy some shares I have one warning. NYX reports its latest quarterly earnings results on Tuesday, Election Day. If the company disappoints or if its forward guidance isn't encouraging enough, the stock could move lower in reaction. The opposite scenario could see a sharp spike in shares.
