James Fishback, the former Greenlight analyst who said he was the head of macro, filed an arbitration claim against his old firm. AdvertisementThe age discrimination claim, according to the filing, is based on a flippant comment Fishback alleges Einhorn made. Fishback told potential backers of his firm he was the head of macro when he was at Greenlight, which prompted the now-viral dispute. The latest legal filing uses the titles "head of macro trading" and "head of macro" interchangeably.
