Between 1980 and 2012, for instance, the 7,706 companies that debuted on public markets jumped an average of 17.9 percent on their first day of trading, according to research by Jay Ritter, a finance professor at the University of Florida who has tracked IPOs. More recently, average first-day gains have fallen, from 70 percent during the dot-com bubble in 1999 to a little more than 15 percent in 2012, Ritter noted.
