LinkedIn profile

LinkedIn's share prices has fallen by more than a quarter after it said profits for the first quarter of the year would be lower than expected.

The professional social media site said its earnings for the first three months would be around $0.55 per share, compared with analysts' forecasts of $0.74.

It adds to growing concerns over the company's profitability, after it reported a $8 million (£5.4m) loss for 2015, compared with a $3m profit in 2014.

LinkedIn chief executive Jeff Weiner said: "We enter 2016 with increased focus on core initiatives that will help drive growth and scale across our portfolio."

The social platform has been expanding its business outside the US, which looks set to continue in 2016. But LinkedIn will miss out on $50m worth of sales in the short-term as it phases out an unsuccessful ad service.
