After having just five IPOs this year, there are now three IPO's on the calendar for this week. This is the most IPO's set for release in one week in over 4 months.

Currently listed on the AIM (Alternative Investment Market) in London with a $2.1 billion market cap, Hutchison China MediTech (HCM  ) is a Chinese pharmaceutical with a pipeline of oncology drugs. Hutchison is looking to raise $100 million, representing the second largest offering this year behind fellow Chinese biotech BeiGene (BGNE  ), which raised $158 million and has traded up 16% since its offering.
