My Top 10 CEOs of 2011
MasterCard (NYSE: MA) CEO Ajay Banga topped Fool contributor Sean Williams' list of top 10 CEOs of 2011. Read about Nos. 1-5 and Nos. 6-10.

"[L]eading MasterCard since only July 2010, he has been nothing short of remarkable," Sean wrote, citing MasterCard's crushing Wall Street consensus estimates and clocking a "ridiculous 67% stock gain [in 2011] while nearly every other financial stock plummeted." And Sean says the MasterCard growth story is just getting started.

Also in Sean's top 10:

  • Jeff Bezos of Amazon.com (Nasdaq: AMZN): Amazon asserted its dominance, caused woes for competitors including Netflix, and set itself up for big growth.
  • Mark Zuckerberg of Facebook: "No decision could have been smarter for Facebook's future value than to delay its IPO filing until the market is more accepting of Internet IPOs," Sean wrote.
  • James Rogers of Duke Energy (NYSE: DUK): Duke increased its dividend and announced a proposed merger with Progress Energy that will, if approved, create the country's largest utility, yielding "operational synergies" and boosting the bottom line.

Check out the stories (here and here) to see all of what Sean had to say about the top 10 CEOs of 2011.

Starbucks' $50 Billion Opportunity
Motley Fool analyst Jason Moser is keen on Starbucks' (Nasdaq: SBUX) strategy of using its $30 million purchase of Evolution Fresh to get into the health and wellness market, which could be a $50 billion opportunity. "I think Starbucks is realizing this is a big market," Jason said during a video conversation with Fool editor Eric Bleeker. "This is a way people are moving. They're trying to live healthier lives, so this is [Starbucks'] first shot at it."

After a Decade of Stagnation, Is This Tech Titan a Buy, Sell, or Hold?
The subject of the headline question is Microsoft (Nasdaq: MSFT), and the answer to the question is "hold," according to Fool contributor Evan Niu. "Some of the company's prospects look promising, particularly those that focus on the inevitable migration to the cloud," Evan wrote. "Having a strategy is just the first step, though, and Microsoft needs to execute flawlessly to compensate for being so late." Shares look too cheap to justify selling, Evan noted, and Windows 8 could do better than expected.

In Foolish fashion, Evan looked at arguments from all sides of the "buy, sell, or hold" question. Read the article to get the lowdown and see whether you agree with Evan.
