Starting as an options clerk-trainee at O’Connor in 1984, Margery Teller spent over 20 years on the floor of the Chicago Mercantile Exchange, where she rose to prominence as the pit’s largest back-month Eurodollar trader.
At her zenith, she accounted for over 10% of the total Eurodollar volume and held open positions bigger than many money-center banks, leading the interest rate community to dub this diminutive woman "Large Marge.” She was so important to the liquidity of the pit that when she first retired in the wake of 9/11, the Merc devised an incentive program to lure her back. She continued to trade in the pit until 2006, when most of the volume shifted to the screen, leaving trading for good in 2010.
Today, she divides her time among various creative projects based on her experiences in the Merc; she also serves as Chair of Friends for the Cure, a group focused on funding research to end Type 1 diabetes, which she founded after her daughter was diagnosed with this devastating disease. To date, the group has raised over $3 million.
