Exchange Consolidation

BATS and Direct Edge, two large electronic exchanges, are merging to form the second largest exchange operator in the United States, taking over the ranking currently held by Nasdaq. This change exhibits the transformation of the industry toward electronic trading. While electronic increases speed and likely lowers trading costs, it doesn't come without risks, as the recent Nasdaq outage illustrates. See article here, Wall Street Journal.

Even Adults Like "Happy Meals"

Higher risk companies, in order to sell bonds at lower interest rates, must often attach "sweetners" to the bond offering. Historically this has included warrants or conversion options. Recently, however, some companies have offered a combination of bonds and a loan of the company's shares, a so-called "Happy Meal." The bond buyers subsequently sell the shares short. If the company fails, the investors lose on the bonds, but make a profit on the short sale. This strategy is typically employed by hedge funds. See article here, Wall Street Journal.

P/E Ratios

Most investors know that the PE multiple is the ratio of price to earnings. While the market price is easy to agree upon, the earnings number that should be used in the ratio is not. Some investors prefer historical earnings, while others focus on forecasted earnings. Each of these approaches can provide widely different PE estimates, making comparison difficult.
