IPO investors will have a different focus this week.

There were two names that were able to raise $380 million last week as we enter the slow period for IPO's. While the deals were small they were still successful and for now IPO investors and analysts are content with the overall health of the markets. As we look over the month so far we have seen $1.1 billion raised by a total of six new offerings. While the deal sizes are larger, the number of deals is still pretty low relative to previous years.

As expected there are no IPO's that will be launching this week which is normal for the next few weeks. This doesn't mean that there will be no activity though. IPO investors will still be focused on filings as a barometer to the overall health of the IPO markets going forward. Many IPO analysts expect that the filings overall will be healthy this week as companies plan their launches post-Labor Day.

As an IPO trader, during this time the focus tends to shift towards recent IPO's and the expiration of their lockup periods. This week there are three names that will see their quiet periods expire, but not all of them will get focused attention. Sienna Biopharmaceuticals (NASDAQ: SNNA), RBB Bancorp (NYSE: RBB), and Redfin (NASDAQ: RDFN) are the three names.
