IPO fever is back.
Five years after the financial crisis dampened enthusiasm for initial public offerings, investors are again eager to buy shares when companies start trading. Twitter is the star this week, but the number of offerings shows that it's not just social-media darlings that are seeking and attracting investors.
There have been 190 offerings this year, and momentum has built as market indexes have set new highs. October's 33 offerings made it the busiest month since November 2007, according to Dealogic. And a dozen expected offerings this week tie it for the busiest week of the year.
