LinkedIn has started 2016 in less than stellar fashion.

Despite punching above expectations on income and revenue, LinkedIn stock still tumbled 40% following its fourth quarter earnings report.

Missing Link

The fall, which reportedly wiped US$10 billion from LinkedIn's coffers, was the result of mediocre outlook and earnings guidance.

The slump marked the worst day for LinkedIn shares since the company went public in 2011.

It's all about Connections

Still, it's not all bad news for the social network for professionals.

LinkedIn is predicting revenue of US$830 million for the first quarter of 2016 which, while below expectations, still marks a rise from 2015.

Yet Twitter's ongoing financial struggles show how unforgiving investors can be, even if you have Kanye and Kim tweeting regularly.
