With eight companies still on the calendar for May, there is a possibility this month could be the first since May 2007

Seven deals began trading on Thursday, marking the most IPOs to debut in a day since December 15, 2004. Thursday's group included single-family residential REIT American Residential Properties (ARPI), packet-optical networking vendor Cyan (CYNI), frac sand LP Emerge Energy Services (EMES), mortgage producer and servicer PennyMac Financial Services (PFSI), the world's largest contract research organization Quintiles Transnational (Q), biotech Receptos (RCPT), and branchless bank TriState Capital (TSC).

TriState Capital was the best performing deal, finishing the day up 9.5%. Receptos (traded flat), American Residential Properties (flat) and Emerge Energy Services (-2.7%) all priced below the midpoint and failed to gain traction throughout the day.

Quintiles and Receptos price upsized deals at opposite ends of the range

Following last week's market break, U.S. IPO activity resumed where it left off last week with five pricings, including ING U.S. (VOYA), which raised $1.3 billion. However, overall performance was subpar, with four of five of the deals achieving a total return of 6% or less and three of five IPOs failing to achieve a 1% first-day pop despite pricing sensitivity (three deals priced below the range). New deal activity, though, remained robust as five companies were added to the calendar, including American Residential Properties (ANRPZ.OB), which is looking to raise $301 million and become the second single family-focused REIT to list this year. Last week also saw four new filers, most notably Apollo-backed teen jewelry retailer Claire's (CLEA.PK), which filed for an IPO that we estimate could raise as much as $500 million.

Despite no new pricings or filings, the U.S. IPO market remained active last week as six companies launched deals. Most of the $1.3 billion in proceeds added to the calendar came from biopharmaceutical service provider Quintiles (Q), which is seeking $750 million. Aside from very fast growing tech company Cyan (CYNI), the remaining new deals were smaller, niche offerings, including two REITs, a development-stage biotech and a regional bank.

The successful IPOs of Fairway Group (FWM), Blackhawk Network (HAWK) and SeaWorld Entertainment (SEAS) served as positive bookends to a mixed week in the US IPO market. For the second week in a row, six IPOs priced, but Thursday's three deals from Taminco (TAM), Intelsat (I) and Hannon Armstrong (HASI) all raised much less than expected and produced lackluster returns. ING U.S.'s (VOYA) planned $1.4 billion IPO was the most prominent of four deals added to the IPO calendar. The week also saw four new filings, which included a $5.4 billion deal from Brazil's Votorantim Cimentos (VOTO.RC) and the first filing from China since YY (YY) in October 2012.

For the third time in as many months, three deals debuted on the same day. The February trio -- mortgage REIT Zais Financial (ZFC) at -6.1%, LP New Source Energy (NSLP) at -2.6%, and medical insurance provider Health Insurance Innovations (HIIQ) at -2.1% -- performed poorly on their first day of trading. The March group did not fare much better, as communications company West Corp. (WSTC) at -5.7% and mortgage REIT Five Oaks Investment (FOIC) at -3.3% traded down in their debuts. However, on-demand ad management firm Marin Software (MRIN) at 16.1% attempted to redeem the group.

Although the April threesome of chemical producer Taminco (TAM), clean energy REIT Hannon Armstrong (HASI), and satellite services provider Intelsat (I) hoped for a different fate, they failed to escape the trend.

All but one traded up, and two, biotech Chimerix (CMRX) and enterprise SaaS company Rally Software (RALY), gained more than 25%. Four new deals were added to the IPO calendar, and some big names such as SeaWorld (SEAS) and Blackhawk Network (HAWK) are scheduled to price this week. A new $1 billion deal from private equity-backed industrial distribution company HD Supply (HDS.RC) helped to sustain a surge in new IPO filings. Including seven last week, 15 companies have filed so far in April, which is already tied for the highest monthly total since August.

The spike in filing activity featured four very fast-growing technology companies, including three enterprise software vendors and a next-generation telecom equipment supplier. Independent Bank Group (IBTX), a small Texas bank, was the week's lone IPO pricing. It priced at the high end of the range to raise $83 million, and traded up 10%.
