Tech stocks: Einhorn speaks out on Apple lawsuit

How are Apple stocks faring the morning after billionaire hedge fund manager David Einhorn sued over the company's cash stockpile? Here's a look at the markets Friday morning:

Einhorn defends Apple suit. In an email exchange with Business Insider, Einhorn of Greenlight Capital suggests Apple has more than enough money to provide preferred stock to shareholders.

"I am aiming for a clever solution where Apple gets to keep its war-chest (which it says it needs) and shareholders can get the value unlocked," Einhorn tells Business Insider.

In a separate report from Reuters, Einhorn claims he received the "brush-off" after urging Apple CFO Peter Oppenheimer for months to offer preferred shares. That's when Einhorn contacted Apple CEO Tim Cook, whom he claims was more open to the proposal.

Following the announcement of Einhorn's lawsuit, Apple responded with a statement saying it will "thoroughly evaluate" the preferred stock option. A brief surge in after-hours trading Thursday has cooled this morning, with the stock up to $472.

LinkedIn soars. The hot streak for the professional social network continues, with shares trading up 10% at above $137 as the markets prepare to open.

The company's fourth-quarter earnings finished well above investor expectations, shooting the stock price up $13 since the close of the markets on Thursday.

LinkedIn generated $304 million in revenue, up 81%, and netted $11.5 million in profit, up 66% from the same period the year before.
