This morning, the Wall Street Journal reported on tension at the top of one of world’s most successful hedge funds. David Magerman, an Orthodox Jewish computer scientist who helped write the trading systems that made the legendary Renaissance Technologies a billion-dollar investment success, was at loggerheads with its CEO Robert Mercer. The point of contention: Mercer and his family’s generous support for Donald Trump, which Magerman asked him to stop.
On Thursday morning, after an online version of this story appeared, Mr. Magerman received a new phone call from Renaissance. A representative told Mr. Magerman that he was being suspended without pay and no longer could have contact with the company.
