The following video is from Tuesday's Investor Beat, in which host Chris Hill and analysts Jason Moser and Matt Argersinger dissect the hardest-hitting investing stories of the day.

Zynga shares rise 20% on news that Don Mattrick is leaving Microsoft to head up the embattled online game company.

In our lead story on Investor Beat, Jason and Matt take a closer look at two CEOs in the spotlight.
