As we plunge into the thick of the summer months many IPO investors have to get comfortable with the summertime slowdown. It is common to see a slowdown in IPO launches as well as a decrease in overall market volume. So far this summer the markets, as well as the IPO markets have been right on track with its typical summer performance. That being said, IPO's don't come to a halt, just a slowdown, and this week we still have two small IPO's launching.

One of the big focus IPO's would be Frontier Group (FRNT  ), and airline that could have a deal size over $500 million.
