Shares in person-to-person internet auctioneer eBay Inc soared 46% yesterday in anticipation of a good set of third quarter numbers from the company after the markets close today and an initial buy rating from Donaldson, Lufkin & Jenrette analyst Jamie Kiggen. He gave the San Jose company a 12 month price target of $100. eBay went public on September 24 at $18, breaking a month-long moratorium on IPOs across all industries, the longest break for almost 30 years. According to the survey of analysts conducted by the not-always-reliable Zacks Investment Research, eBay is expected to earn three cents per share. The stock closed yesterday up $23.25, or 46.4% at $73.375.
