VMware, EMC, Yahoo!, Facebook: Tech Premarket

NEW YORK ( TheStreet) - VMware ( VMW) was a big loser in premarket trading Tuesday, plunging more than 18% following the software maker's fourth-quarter results released late on Monday.

For the first quarter, VMware said it expects sales between $1.17 billion and $1.19 billion, below analysts' forecast of $1.25 billion. VMware also is looking for fiscal 2013 revenue of $5.23 billion to $5.35 billion, well below Wall Street's prediction of $5.42 billion.

Investors were less than impressed with the results, pushing VMware's shares down 18.67% to $79.96.

VMware's parent company EMC ( EMC) was also off in premarket trading after reporting its own fourth-quarter results. The storage giant edged past Wall Street's estimates, although its shares tumbled on weaker-than-expected guidance.

EMC shares slipped 5.56% to $23.8 before market open.

Yahoo! ( YHOO), however, was a big gainer, rising 3.05% to $20.93 following the company's better-than-expected fourth-quarter results on Monday. The Sunnyvale, Calif.-based firm was also one of the most active premarket Nasdaq stocks on share volume of 767,745.

Facebook ( FB), which reports its fourth-quarter results on Wednesday, dipped 0.49% to $32.31 on share volume of 739,092.

Research In Motion ( RIMM) which unveils its eagerly anticipated BlackBerry 10 technology on Wednesday, gained 1.05% to reach $16.35 on share volume of 182,254.

Shares of Amazon ( AMZN), on deck to report its fourth-quarter results after market close, crept up 0.53% to $277.50 in premarket trading.
