8-10-95. NYPaper Page-Oner: "With Internet Cachet, Not Profit, New Stock Is Wall St.'s Darling." A 15-month-old company that has never made a dime of profit had one of the most stunning debuts in Wall Street history yesterday as investors rushed to pour their money into cyberspace. The Netscape Communications Corporation became the latest -- and hottest -- company in the Internet business to list shares on the nation's stock exchanges. Shares of Netscape, which had been priced at $28 before trading began at 11 A.M. opened far higher -- at $71. The shares soon surged to as high as $74.75. It was the best opening day for a stock in Wall Street history for an issue of its size. But even more significantly, it was a sign of how the rush to commercialize the global computing web known as the Internet has created an investor frenzy not seen in the technology industry since the early days of the personal computer more than a decade ago. "There is a mania under way," said Michael Murphy, the editor of The Overpriced Stock Service, a newsletter in Half Moon Bay, Calif. The company's co-founder and chairman, who holds 9.7 million shares, ended up holding a stake valued at a half-billion dollars. Making his first fortune yesterday was Marc L. Andreessen, Netscape's 24-year-old vice president of technology and an inventor of its prize software. Based on yesterday's closing price, his interest in Netscape is worth more than $58 million.
