Marc Rich & Co.
Fortune reported in 1988:
- Now in his 30s, Weiss is a close friend and protege of Pinky Green. It was Weiss who did the firm's first metals deal, shortly after joining Marc Rich in 1975 as a teenage messenger in London. That year, while his boss vacationed, Weiss took charge of a telex from an East bloc country requesting zinc. He arranged the shipment, generating a fat profit.
In the mid-1980s, Weiss spearheaded a strategy by which Rich affiliate Clarendon Ltd paid US smelters to process cheap Jamaican alumina during a glut in the market, establishing contractual arrangements which proved immensely profitable once the market recovered.
Weiss later lost at least $25 million by shorting aluminum when the price dipped after the 1987 stock market crash only to recover the following year.
He left the company in 1992.
