It's another slow week coming up for the IPO markets, which usually join the broad markets in taking a break for the few remaining weeks until the summer is officially over. IPO markets should pick up activity just about the same time as the stock market. The stock market usually become more active and volatile just after Labor Day, but with the IPO markets we can tell ahead of time with more specificity if they will actually be active with new potential offerings.

This week will be a good indicator for the post-Labor Day IPO activity. By seeing which companies file this week, we will have a good idea how many will price after the holiday.

There are just three potential names coming out this week, and it's likely that none of them will garner real attention from investors.

The largest offering for the week is Megalith Financial Acquisitions (MFACU  ), a company formed for the sole purpose of finding and acquiring financial services businesses. They are looking for $150 million by offering 15 million shares at $10.

The second largest offering is Tenzing Acquisition (TZACU  ), which is also a company formed with the sole intention of buying other companies. Tenzing is focused on the acquisition of businesses in India. They will offer 5 million shares for $10 in hopes of raising $50 million.

The last name is a small biotech company. Bionano Genomics (BNGO  ) has continued to delay their IPO, and very well could do the same this week. This company offers a proprietary DNA system and is looking for $16 million. They will offer 2.5 million shares at a range of $6 to $7.
