Yelp’s second-quarter loss widened as the local-reviews website saw surging expenses continue to outpace better-than-expected revenue.

But shares jumped 14.8 percent to $21.60 after hours yesterday, after the company boosted its full-year guidance and posted an upbeat forecast for third-quarter revenue.

Yelp reported a first-quarter loss of $2 million, compared with a year-earlier loss of $1.2 million.
