The top 10 first-day gains for U.S. initial public offerings all took place in the past 13 months, a testament to the explosion of online trading and the high-profile media coverage of technology companies.

Six of the big ones occurred in October-November as the stock market continued its love affair with nearly all things Internet, according to Hoover's Online.

Theglobe.com, which builds online communities, kicked off the trend a year ago, setting a record that still stands with a 606 percent jump on its first trading day--Nov. 13, 1998. The most recent company to hit the top 10 was CacheFlow Inc., in the hot business of making products that speed up the Internet. It rose 427 percent on its first day--Nov. 19, 1999--to claim the No. 6 spot.

Others making the list were Foundry Networks Inc., a manufacturer of switches and routers; Cobalt Networks Inc., which makes Linux-based servers; MarketWatch.com, a financial information Web site; Akamai Technologies, which aims to eliminate Internet data bottlenecks; Sycamore Networks Inc., which makes products to expand bandwidth for fiber-optic networks; Ask Jeeves Inc., a Web search engine; Finisar Corp., a manufacturer of high-speed networking equipment; and Crossroads Systems Inc., which provides data storage.
