``UBS AG's $2 billion loss from what it said was unauthorized trading prompted Swiss lawmakers to call for tougher capital requirements and for other businesses to be protected from riskier investment banking operations. Switzerland's biggest bank said today it may be unprofitable in the third quarter after the loss from "unauthorized trading" at its investment bank. UBS tumbled as much as 9.6 percent in Swiss trading following the announcement.''
