Insider Trading

SAC Capital ex-trader convicted of insider trading

Scuffle breaks out after Martoma trial

A former SAC Capital Advisors portfolio manager was convicted Thursday of helping his company earn more than a quarter of a billion dollars illegally through trades based on secrets about the testing of a potential breakthrough Alzheimer's drug.

A federal jury in Manhattan found Mathew Martoma, 39, guilty on all three of the conspiracy and securities fraud charges that he faced, in what prosecutors said was a scheme that netted SAC Capital $275 million.

The verdict capped a three-week trial that featured testimony from two prominent doctors who confessed spilling secrets to Martoma during lucrative consultations with financiers.

Martoma faces up to 45 years in prison.

"Cheating may have been profitable for Martoma, but in the end, it made him a convicted felon, and likely will result in the forfeiture of his illegal windfall and the loss of his liberty," said Manhattan U.S. attorney Preet Bharara, in a statement.

Martoma becomes the 79th person convicted of insider trading after trial or by guilty plea in the Southern District of New York over the past four years.

When asked to comment on the verdict, Richard Strassberg, a Martoma defense lawyer, said, "We are disappointed and are planning an appeal."

SAC declined to comment to CNBC on the verdict.

Martoma sat expressionless as the jury forewoman announced he had been found guilty of two counts of securities fraud and conspiracy to commit securities fraud. Tears streamed down the face of his wife, who sat with her hands folded on her yellow dress.

The trial also contained frequent mentions of SAC Capital's billionaire founder, Steven A. Cohen.

Strassberg said in his closing argument Monday that Cohen was the real target of investigators. He said his client was victimized by the testimony of doctors who traded their credibility for plea deals that left them beholden to the government.

The doctors learned "just how frighteningly scary it can be if you get in the way of a government investigation that's targeting someone like Steve Cohen," Strassberg said.

Sidney Gilman, an 81-year-old former professor of neurology at the University of Michigan Medical School, testified that he gave Martoma the secret results of the drug trial sponsored by drug makers Elan and Wyeth nearly two weeks before they were publicly announced.

He said he was charmed by Martoma, who seemed more knowledgeable about his work than hundreds of others in the financial community who paid Gilman more than $1 million over several years for consultations.

Gilman said he could not recall giving similar information to anyone else, though he conceded that he "perhaps unintentionally ... may have slipped here and there."

Assistant U.S. Attorney Arlo Devlin-Brown told the jury that after the doctor showed Martoma the test results in one of 43 consultations the pair had, Martoma sent Cohen an early morning email asking: "Is there a good time to catch up with you this morning? It's important." A half hour later, they spoke for 20 minutes on the phone.

The next day, Devlin-Brown said, Martoma and SAC Capital began selling all their shares in Elan and Wyeth and building a short position that would make millions of dollars when the stock of both companies plummeted following the public announcement of the drug trial's results. The government said the trades on both ends earned $275 million in profits, enough to score a $9.3 million bonus for Martoma.

"Ladies and gentlemen, Mr. Martoma, though all of this circumstantial evidence, has been caught with his hand deep inside the cookie jar, and defense counsel wants you to think that maybe he was just putting the cookie back," Devlin-Brown said in his closing. The prosecutor said Gilman, formerly one of the top Alzheimer's researchers in the world, has all but ended his career. "He's 81, and he's humiliated."

Strassberg told jurors Gilman's "story at its heart makes no sense" because his memory was flawed when he met with Martoma in 2008 while he was undergoing chemotherapy for successful cancer treatments.

Another doctor, Joel Ross, testified that he also gave Martoma secrets about the Alzheimer drug test, in part because he hoped Martoma would connect him with biotechnology companies that might provide business for his new drug research center in Eatontown, N.J.

Who is Mathew Martoma really?

SAC Capital pleaded guilty in November to fraud charges and agreed to pay $1.8 billion to settle charges that it allowed, if not encouraged, insider trading for more than a decade.

Cohen has not been criminally charged, but the Securities and Exchange Commission has accused him in a civil action of failing to prevent insider trading at the company, which he founded in 1992 and bears his initials. Cohen has disputed the allegations.

Strassberg told jurors that Martoma, born to immigrants in Florida, was a "quintessential American success story" and that they could acquit him based on even one of "dozens and dozens" of inconsistencies in Gilman's testimony.

Tense courtroom for Mathew Martoma trial

"Mathew's life is on the line," he said, as he hinted that a conviction could bring a lengthy prison term because insider trading is "deadly, deadly serious."

"I'm going to put his life in your hands," Strassberg said.

Then, speaking like a basketball coach insisting that his team not lose at home, he told jurors to reject the government's version of events and "stand up and to do justice. I ask you to tell them, 'No, not in this courtroom, not while you are the jurors!' "

There was no mention at trial of Martoma's educational record at Harvard Law School, where he was expelled in 1999 after he used a forged transcript he claimed he created to impress his parents to apply for a clerkship with as many as 23 federal appeals judges.
