The IPO business started with a whimper, but has ended with a bang in June. Last month was the busiest for IPO issuances since 2000, with 35 deals.

So far this year, 104 IPOs have raised $18.1 billion, according to Renaissance Capital, the IPO ETF provider.

If this keeps up, we will likely end up with over 220 deals in 2015, not quite last year's 275 deals, but still respectable. 2014, by the way, was the biggest year for new issues since the dot-com era.

This morning, for example, Spanish language broadcaster Univision Holdings filed for an IPO of up to $100 million, though that figure will likely change.

Over 120 companies have registered for an IPO, including several well-known names.
