TODAY'S CHARTS: GoPro pops on revenue beat; Yelp surprises with profit; Weight Watchers wows with subscriber growth

We’re wrapping up another major week of earnings. Here are some of the biggest movers today.

GoPro (GPRO) is set to make one of its biggest gains of the year, up 17%. The action camera maker reported a smaller loss than expected on a big revenue beat. GoPro also said it’s on track to launch its highly-anticipated camera, the Hero6, by the holidays.

Meanwhile Yelp (YELP) is up 27% after surprising investors with a profit, rather than the expected loss, while revenue also came in strong. On top of all that, Yelp announced $200 million in stock buybacks and a deal to sell its Eat24 business to GrubHub.

Finally, Weight Watchers (WTW) is another big mover to the upside, surging 27% after posting a beat on both its top and bottom lines. The diet systems company also reported its subscriber base grew 20% and raised its full-year outlook.
