IPO Lookout: IPOs for the Week of March 31

Nine more IPOs will be available to traders in the secondary market this week as the total number of year-to-date offerings rises from 75 to 84.

So is the slight decrease a sign that the IPO market is cooling off? Not a chance. Last year, from Jan. 1st to March 31st, there were 43 IPOs and this exact same week one year ago saw only two IPO deals hit the market.
