In this video from Tuesday's edition of Investor Beat, host Chris Hill and Motley Fool analysts Mike Olsen and Morgan Housel dig into the biggest business stories from Tuesday's market facing Foolish investors today.

Microsoft has now appointed its new CEO, 22-year Microsoft veteran Satya Nadella, who replaces outgoing Steve Ballmer to be only the third CEO in the company's nearly 40-year history. Meanwhile, Bill Gates will exit his position as chairman of the board and move to a new role as technology advisor. In the lead story on today's Investor Beat, the guys discuss what initiatives they're hoping to see from Nadella, and why he may have been too conservative a choice for the company to have gone with.

Then the guys discuss four stocks making moves on the market today. J.C. Penney hit a fresh 52-week low today, after same-store sales for the fourth quarter rose by only 2%. Shares of Michael Kors were up big today, after third-quarter profit rose by 77%, with same-store sales in North America up by 24%. On Monday, RadioShack got a lot of praise for its Super Bowl commercial, but today The Wall Street Journal is reporting that the company plans to close about 500 of its 4,500 stores. And happy birthday to Facebook! The social network turned 10 today and got a boost to its share price as a birthday present.

Finally, Mike tells investors about the virtuous cycle that allows Progressive to grow and pass savings along to consumers, while Morgan discusses MasterCard, and the opportunity ahead of the company now that the economy is recovering and its lagging credit card business has a chance to catch up as consumers have more of an ability to pay off their debts.
