In a sign of strong demand, Optium Corporation priced its 5.2 million share offering at $17.50, a 21% premium to its proposed $13.50 to $15.50 range. Optium provides a full suite of high-performance optical subsystems that perform transmission and switching functions in long-haul, metro and access telecom and cable TV networks. Morgan Stanley and Credit Suisse acted as joint book-running managers for the IPO, and the stock is expected to commence trading on the NASDAQ under the ticker symbol "OPTM" on Friday.
