Make millions, lose millions, who cares, what's the point of it all? Greg Coffey, co-chief investment officer of Moore Capital Management LLC’s European business, is leaving the hedge-fund industry after a 20-year trading career, according to a letter sent to investors...Assets in Coffey’s macro fund have slumped to about $100 million from as much as $1.6 billion in 2010. The fund had fallen about 10 percent this year through August before rebounding almost 9 percent last month, according to people with knowledge of the matter, who asked not to be named because the information is private. The fund lost 5 percent last year. Coffey realized that after he had recovered most of this year’s losses in one week in September, he wasn’t as excited about his gains as he might have been in the past, two people who know him said. Coffey then decided it was time to end his 20-year career trading, the people said. Moore Capital’s Coffey to Retire From Hedge-Fund Industry [Bloomberg]

Back in May 2010, a Wells Fargo employee named Waldyr Da Silva Prado Neto got a hot tip that Burger King was going to be bought by private equity firm 3G Capital Partners. Realizing he was in possession of some valuable information, Da Silva Prado Neto did what any rational person with an elastic view of securities laws would, and shared the material non-public information with some clients and friends, making about $175,000 and also putting himself in the good graces of pal he tipped off, who probably promised to return the favor. DSPN used Portuguese to communicate the message that he had information that might be of interest ("If you are around call me at the hotel," he emailed one customer. "I have some info…you have to hear this"), which seems pretty standard, given that he's Brazilian, though at least one person at the SEC is pretty sure it was an attempt to throw regulators off the trail, not realizing the lengths the Commission will go to to fight crime. "Prado's emails and other communications may have been sent from Brazil and written in Portuguese, but our commitment to prosecute illegal insider trading on U.S. markets knows no geographic or language barrier," said Sanjay Wadhwa, deputy chief of the SEC enforcement division's market abuse unit.
