If all 21 deals go off, which would be a feat in itself, it would be the busiest week in quite some time, even rivaling the 20 and 17 IPOs that were sold in all of February and January, respectively, says Renaissance Capital.
Investors would have to go back to the week of Nov. 12, 2007 to remember a week with more IPOs, 21, says IPOScoop.com.
There are some big deals among the bumper crop of IPOs. Ally Financial, the former financing arm of General Motors, is expected to raise $2.5 billion by selling 95 million shares between $25 to $28 a share. This deal will be a good test of investors' appetite for deals, since the company has been trying since 2011 to sell shares to the public.
Another headliner deal is hotel chain La Quinta, which is being brought to market by private equity firm Blackstone. The company said it will sell 37.2 million shares at an expected price range of between $18 and $21 a share.
