(SUNW) - Get Report

earnings were so bright, traders donned sunglasses to trade it. It was up 5.9375 to 104 on 1,185,729 Instinet shares.

The server maker not only surpassed earnings estimates but broke through the $5 billion revenue mark for the first time, up 42% year over year. Net income for the fourth quarter rose 67% to $659.5 million, or 39 cents a share, excluding gains on the sale of equity investments and acquisition-related charges for fiscal year 2000. Analysts had estimated it would make 33 cents a share.

The bullish results were not an enormous surprise to investors who bid the stock up 4% today in anticipation of a positive quarter. However, analysts may have been a bit stunned by the robust revenue, which they expected to be about a billion dollars lower. The company boasted gains in market share, catapulting the company from the No. 4 open system provider to No. 1, according to CEO Scott McNealy. The company also forecasted 30% growth in coming quarters.
