NEW YORK (TheStreet) -- Shares of VMware (VMW) - Get VMware, Inc. Class A Report are plunging, down 5.19% to $76.43 in late morning trading Wednesday, after the information technology company was downgraded to "hold" from "buy" by analysts at Needham this morning.

The firm lowered its rating following VMware's fourth quarter earnings results and a disappointing calendar year 2015 outlook.

Separately, TheStreet Ratings team rates VMWARE INC as a Hold with a ratings score of C. TheStreet Ratings Team has this to say about their recommendation:

"We rate VMWARE INC (VMW) a HOLD. The primary factors that have impacted our rating are mixed, some indicating strength, some showing weaknesses, with little evidence to justify the expectation of either a positive or negative performance for this stock relative to most other stocks. The company's strengths can be seen in multiple areas, such as its robust revenue growth, largely solid financial position with reasonable debt levels by most measures and expanding profit margins. However, as a counter to these strengths, we also find weaknesses including a generally disappointing performance in the stock itself, unimpressive growth in net income and disappointing return on equity."
