This Week’s 5 Dumbest Stock Moves: Coinstar, Inc. (CSTR), iRobot Corporation (IRBT) and More

4. Facebook Inc (NASDAQ:FB) takes over the Web
For a brief moment in time on Thursday night, Facebook was taking over the Web.

Several major websites with Facebook Connect buttons — Fool.com included — were taking folks logged in to the social networking website back to Facebook with an error message. Was it a hack? Did everyone spring a flat on the information superhighway? No.

Facebook provided a brief explanation shortly after the redirections ceased: “For a short period of time, there was a bug that redirected people logging in with Facebook from third party sites to Facebook.com. The issue was quickly resolved, and Login with Facebook is now working as usual.”

The matter was resolved quickly, but it’s not looking good for Facebook. It’s a glitch that may force leading websites to reconsider their alliances with Facebook Connect, especially if it repeats itself.

5. Ay, robot
Shares of iRobot Corporation (NASDAQ:IRBT) rebooted yesterday, falling 13% after the company behind the Roomba and military robotics offered weak guidance.

iRobot’s guidance for the current quarter is short of where Wall Street was perched, and it’s a mixed outlook for all of 2013.

The problem at iRobot is the sharp drop in military robot orders. Given government spending cutbacks, many defense contractors have been sputtering. iRobot does have its line of consumer products doing well. The home robotics segment rose 28% during the holiday quarter and iRobot’s CEO expects that division to grow at a 20% clip this year and account for 90% of the overall revenue. This should make comparisons easier come 2014, but for now the market’s worried about iRobot’s softness for the current quarter.
