Three deals were on the IPO calendar to price on Tuesday night, but failed to do so. Sol-Wind Renewable Power LP (SLWD) is now tentatively targeting tonight, Wednesday, February 11. AutoGenomics (NASDAQ:AGMX), which makes genetic testing systems, may price this week. Gene testing IPO AltheaDx (NASDAQ:IDGX) officially postponed its offering. AltheaDx was one of seven health care IPOs that failed to price last week. The week ahead still features the week's most exciting IPO, Inovalon (NASDAQ:INOV), which raised its range on Tuesday morning and is expected to price tonight. Yet another gene testing company, Invitae (NYSE:NVTA), could also raise interest if investors favor a more consumer-focused business.
