Steve Cohen’s frat star days

This is Steven A. Cohen before he gained $9.4 billion and lost his hair.

A classmate from the University of Pennsylvania at Wharton, from which the hedge-fund tycoon graduated in 1978, shared this photo from the Zeta Beta Tau fraternity, where Cohen was treasurer.

“While everyone else was worried that they would not have time to finish a particularly tough statistics exam, Steve took a break from the exam at 4 p.m. to check on his stocks,” my source said.

“It was before cell phones.”

Cohen is helping burnish the reputation of ZBT, which students joke stands for Zillions, Billions and Trillions.

Cohen donated $2 million to the fraternity four years ago, but he has declined to give a dime to Wharton, claiming it didn’t teach him anything. Instead, he donated $30 million to Brown University, from which his son Robert graduated.

SAC Capital Advisors agreed last month to close its investment advisory business as part of a $1.8 billion deal to end a US Justice Department criminal probe into insider trading and money-laundering. Quite a haircut for a guy with no hair.
