Hambrecht & Quist Group’s director of research, Bruce Lupatkin, has resigned from the brokerage firm, a spokeswoman confirmed.

Staff members of the San Francisco-based brokerage were told of Lupatkin’s departure late last week, although there was no official announcement, people at the firm said. The firm is expected to name an interim research director later this week.

Hambrecht & Quist’s stock fell $1 to close at $30.94 on the New York Stock Exchange.
