LinkedIn joins Twitter in post-earnings tumble

NEW YORK — Dumping social media stocks that show any sign of weakness is trending on Wall Street.

Shares of LinkedIn Corp. plunged 21 percent in after-hours trading Thursday after the professional networking service gave a disappointing outlook for the second quarter, weighed in large part by its pending purchase of online learning company Lynda.com, reports AP

Twitter, meanwhile, has lost 23 percent of its value this week through Thursday. The messaging service on Tuesday reported revenue and offered an outlook that fell short of Wall Street’s expectation. On top of that, investors were rattled when Twitter’s earnings report came out inadvertently nearly an hour ahead of schedule.
