"We rate CBOE HOLDINGS INC (CBOE) a BUY. This is based on the convergence of positive investment measures, which should help this stock outperform the majority of stocks that we rate. The company's strengths can be seen in multiple areas, such as its revenue growth, largely solid financial position with reasonable debt levels by most measures, notable return on equity, reasonable valuation levels and expanding profit margins. We feel these strengths outweigh the fact that the company has had lackluster performance in the stock itself."
