Ed Noonan is frustrated. He’s chief executive officer of Validus Holdings (VR), which manages an investment portfolio of insurance-linked securities, among other things. These are more frequently referred to as “catastrophe bonds”; in the event of a natural catastrophe, they offer a return but lose their principal to pay for insurance losses. Validus is being undercut in this market by fund managers who are, according to Noonan, no longer behaving rationally.
