Michelle Williams won the World Cup Championship of Futures Trading in 1997 at age 17 — exactly ten years after her father Larry Williams' record-setting 1987 victory. She turned a $10,000 entry account into roughly $110,000 over the calendar year, a near-1,000% return that made her the youngest WCTC champion in the championship's history and the first father-daughter winning combination in any documented professional trading competition. Unlike her father's continuing public career, Michelle stepped away from the trading spotlight after the win. She is occasionally confused with the actress of the same name (no relation). Her 1997 result is still cited in academic papers on cognitive biases in trading-competition data, partly because the family clustering — both winners at age 17 — is used as a test case in arguments around statistical clustering in performance attribution studies.
