Groupon, Apple, IBM: Tech Premarket

NEW YORK ( TheStreet) -- Groupon ( GRPN) was a big gainer in premarket trading on Friday, rising more than 4% following the ouster of CEO Andrew Mason.

The daily deals site announced Mason's departure in a press release sent out late on Thursday. Groupon's Executive Chairman Eric Lefkofsky and Vice Chairman Ted Leonsis have replaced Mason on an interim basis.

The company's weaker-than-expected fourth-quarter results and guidance earlier this week had prompted speculation about Mason's future. In the release announcing Mason's departure, Groupon noted that its first-quarter outlook remains unchanged.

Groupon's shares gained 4.86% to $4.75 before market open. The Chicago-based firm was also the most active premarket Nasdaq stocks on share volume of 89,523.

Apple ( AAPL) shares slipped 0.62% to $438.65. Credit Suisse cut its estimates for the consumer tech giant on Friday, citing lower iPhone shipments.

Zynga ( ZNGA) shares dipped 1.78% to $3.32 on share volume of 66,297, while Facebook ( FB) was down 1.03% at $26.97.

Shares of IBM ( IBM), which increased its target for big data revenue at its investor briefing on Thursday, dipped 0.31% to $200.2 in premarket trading.
