Initial Public Offerings (IPOs): A lousy start to the year, but that may be about to change. About 15 IPOs have happened so far this year, a poor showing, and of that only a little more than half are trading above their initial pricing. Others have been postponed.

But this is the busiest week of the year in terms of numbers...at least five IPOs are coming, maybe more. What's driving things? As the markets have been higher, there's been some pent up demand emerging, and some indications that pricing may be more rational.
