Nine IPOs are scheduled to price this week, which would be the most in five months according to Bloomberg. So far this month, only 7 IPOs have been priced. Below is a chart showing the number of US IPOs priced on a monthly basis since 1991. As shown, IPOs have bounced back somewhat since becoming non-existent during the financial crisis. Things are still much slower than they were in the mid-2000s, however. The average number of IPOs per month so far this year is 13.75 compared to an average monthly number of 25 from 2004 to 2007. And the mid-2000s were slow as well compared to the 1990s. Who knows if there will ever be another IPO period like the 90s.
