Executives with California United Bank were at the NASDAQ Market Site in Times Square on Oct. 10 to ring the bell at the start of the trading day. California United Chairman, President and CEO David Rainer pressed the button for the bell at 6:30 a.m. “It was a great experience for our bank, which is just over seven years in age and has done so well in such challenging times,” Rainer said in a phone interview later that morning. Encino-based California United began trading on the NASDAQ Capital Market starting Oct. 9 after having traded on the Over the Counter Bulletin Board. The move gives the bank visibility to investors and improves its liquidity with shareholders, Rainer said. California United has eight branches in Los Angeles and Orange counties and a loan production office in Irvine.
