US targets $15m insider trading
The US has charged 14 people for their alleged role in a $15m (7.6m) insider trading racket.
The Securities and Exchange Commission says it is one of the biggest insider trading rings in 20 years and includes top lawyers and finance firms.
SEC enforcement head Linda Thomsen said there was "hardly a duty on Wall Street" the defendants did not breach.
The case claims individuals were given tip-offs about impending deals and stock upgrades, in order to make money.
Top tier
The SEC, which announced the case on Thursday, said insiders from Morgan Stanley and UBS Securities stole secret information from the firms.
"This conduct didn't occur in obscure boiler rooms - but rather at what are commonly considered "top-tier" Wall Street firms, " said Ms Thomsen.
The watchdog also claimed a Banc of America Securities broker took cash and two ex-Bear Stearns representatives got hold of secret UBS information.
The defendants also included three hedge funds, which the SEC said benefited most from the fraud.
The list of those charged includes Mitchel Guttenberg, an executive director and institutional client with UBS, who was charged with accepting hundreds of thousands of dollars as he sold information to David Tandy and Erik Franklin.
They in turn used the information to make money, the SEC said.
Ex-Morgan Stanley employee Randi Collotta and her husband Christopher Collotta were also charged.
A Morgan Stanley spokesperson said: "We are outraged that a former employee allegedly stole confidential information from the firm, and we have co-operated and will continue co-operating with the authorities."
Similarly, Bear Stearns and Bank Of America - Banc of America Securities' parent firm - said they would fully with the investigation.
