What have I been harping on for who knows how long? Activism.

If you were listening, the announcement that Whole Foods Market Inc. (WFM) was be acquired by Amazon.com Inc. (AMZN) shouldn't come as a total surprise. Sure, the buyer isn't the first one that came to mind, but a transaction nonetheless seemed to be in the cards for the grocer, especially after Jana Partners got involved earlier this year.

The Whole Foods-Amazon tie-up marks a win for Jana, but it may not be the last of the year. The firm is also invested in a number of other businesses and you can bet we haven't heard the last of them this year.

While the intent is to to restrict the flow of money to oppressive elements of the Cuban regime and ensure that the statutory ban on tourism is strictly enforced, stricter regulations could have a negative effect on some business that have been betting big on the island nation.

Sure, we've all heard of the pipeline spills and the problems and controversy surrounding the business. But did you know just how bad this issue has gotten at Energy Transfer Equity (ETE)? We've got the story.

In 1981, just a year after its founding, a flash flood severely damaged the original store in Austin. The company, run by long-time friends David Matthis (right) and John Mackey, the current CEO, would reopen the store only 28 days later.
