The following video is from Thursday's Investor Beat, in which host Chris Hill, and Motley Fool analysts Jason Moser and Bryan Hinmon, dissect the hardest-hitting investing stories of the day.

Groupon's second-quarter profits rose just $0.02 a share, and revenue was up just 7% YOY.  But those results, plus the news that interim CEO Eric Lefkofsky had the word "interim" removed from his title, were enough to send the stock to a new 52-week high. In our lead story on Investor Beat, Bryan and Jason weigh the pros and cons of Groupon's latest quarter, and whether now is the time for investors to jump in.

Also, our analysts take a look at four stocks making big moves on today's market. Tesla Motors rises after reporting second-quarter profits. Solar City's second-quarter revenue falls 19%. Green Mountain Coffee Roasters' new CEO gets a thumbs-up. And Beam rises as shares approach a five-year high.

Finally, Bryan and Jason each take a look at one stock they'll be watching closely this coming week.
