Larry Williams: The 1987 World Cup Champion Whose Daughter Won It Ten Years Later

Larry Williams won the 1987 World Cup Championship of Futures Trading with an 11,376% return — turning $10,000 into over $1.1 million in 12 months. The record has never been beaten. Ten years later, his daughter Michelle Williams won the same championship at age 16 (the year before she became famous for Dawson's Creek). Larry also created the Williams %R indicator (1966) and has authored more than a dozen trading books over six decades of active trading.

The Snapshot

Larry Richard Williams is one of the most consequential — and most genuinely entertaining — figures in modern technical analysis. Born October 6, 1942 in Miles City, Montana, he has been actively trading futures and commodity markets for more than six decades and has produced one of the most-cited single-trade records in trading history: the 1987 Robbins World Cup Championship of Futures Trading win, in which he turned $10,000 into $1,137,600 over 12 months — an 11,376% return that remains the highest ever recorded in the championship's history. Wikipedia

Beyond the championship, Williams is the inventor of the Williams %R indicator (1966), which remains one of the most widely-used technical analysis tools across modern trading platforms. He has authored more than a dozen trading books (the most famous being How I Made One Million Dollars Last Year Trading Commodities), pioneered the integration of Commitment of Traders (COT) report data into retail trading methodology, and has continued to actively trade and publish trading research into his 80s. His daughter Michelle Williams — the Academy Award-nominated actress — won the same World Cup Championship in 1997 at age 16, making the Williams family the only parent-child pair to both win the championship.

For traders studying technical analysis lineage, Williams is essential reading because his work bridges the gap between purely chart-based technicians (like Edwards & Magee) and the modern institutional macro approach that integrates fundamental data with technical timing. The Williams %R and COT integration remain foundational components of how serious retail technical traders read markets — and his championship record provides documented verification that the methodology can produce extreme returns when applied with appropriate aggression. The framework is part of the broader trading education canon we cover. Traders Log

Montana to Markets

Williams was born October 6, 1942 in Miles City, Montana, into a family with no Wall Street connections — his father was a small-town merchant. He attended the University of Oregon, studying journalism, and was inspired into trading after observing the 1962 Kennedy steel price rollback, when President Kennedy publicly pressured U.S. Steel and other major producers to reverse a coordinated price increase. The market reaction to the political intervention demonstrated to Williams that political and fundamental forces could produce dramatic price movements in commodity markets, which became one of the structural foundations of his subsequent methodology. Traders Union

What's distinctive about Williams's early career was the speed of his development. By 1966 — only a few years after starting to trade — he had developed the Williams %R, the technical indicator that still bears his name and remains widely used across modern trading platforms. The indicator was created during a period when systematic technical analysis was still relatively rare in retail trading (most retail traders relied on intuition or basic chart reading); Williams's mathematical formalization of an overbought/oversold oscillator was genuinely innovative for the era.

The Williams %R Indicator

The Williams %R (Williams Percent Range) is a momentum oscillator that measures the level of the current closing price relative to the high-low range over a specified lookback period (typically 14 days). The indicator oscillates between 0 and -100, with values above -20 indicating overbought conditions and values below -80 indicating oversold conditions. The mathematical structure is essentially an inverted Stochastic Oscillator, which George Lane developed independently around the same period. The Williams %R remains one of the most widely-used technical analysis tools across modern trading platforms — included by default in virtually every charting package from TradingView to ThinkOrSwim to MetaTrader.

The 1987 Robbins World Cup Championship

The Robbins World Cup Championship of Futures Trading is an annual real-money trading competition launched in 1984, sponsored by the Robbins Trading Company. Participants trade their own accounts (with audited brokerage statements verifying the returns) over 12 months, and the highest documented return wins. The competition's structure — externally-administered, broker-audited, real-money — is meaningfully stronger than typical trading performance claims because it requires actual capital at actual risk through actual market conditions. InsiderWeek

Williams entered the 1987 championship with $10,000 in initial capital and a methodology that integrated technical analysis (his own indicators) with Commitment of Traders (COT) report data. The framework: identify futures markets where the COT data showed extreme positioning by commercial hedgers (who typically know the underlying fundamentals better than speculators), then time entries using technical indicators when the market structure aligned with the COT signal. Over the course of 1987, Williams's account grew from $10,000 to a peak of over $2 million before two final trades reduced the closing balance to $1,137,600 — still an 11,376% return for the year, the highest ever recorded in the championship's history.

Michelle Williams's 1997 Win

The story takes a turn that no one writing about competitive trading in 1987 would have predicted. Ten years later, in 1997, Williams's then-16-year-old daughter Michelle Williams — who would become an Academy Award-nominated actress (Brokeback Mountain, Blue Valentine, My Week with Marilyn, The Fabelmans) — entered the same Robbins World Cup Championship and won it. Her return: approximately 1,000% (some sources cite 900%, others closer to 1,100%), turning $10,000 into approximately $100,000+ over 12 months. The result placed her as the second- or third-highest return in the championship's history (depending on the exact figure used), making the Williams family the only parent-child pair to both win the championship.

Michelle Williams's subsequent career took her away from active trading. She was legally emancipated from her parents at age 15 (one year before the championship), moved to Los Angeles to pursue acting, and starred in Dawson's Creek beginning in 1998 — the year after the championship win. Her trading record is now essentially a footnote in her biographical material, but the structural fact — a 16-year-old winning a competition designed for serious professional commodity traders — remains one of the more interesting data points in the history of competitive trading. The implication isn't that trading is easy at 16; it's that the methodology Larry Williams had developed and taught his daughter was systematic enough to be operationally executable by someone who hadn't spent decades in markets.

The COT and Seasonal Methodology

Williams's actual trading methodology centers on the integration of three structurally important sources: Commitment of Traders (COT) report data, seasonal patterns in commodity markets, and technical timing indicators (including his own Williams %R). The COT data — published weekly by the Commodity Futures Trading Commission — shows the positioning of three categories of market participants: commercial hedgers (who typically have the best fundamental information), large speculators (institutional commodity funds), and small speculators (retail traders). Williams's framework: identify markets where commercial hedgers have extreme positioning, then time entries using technical signals when the broader market structure aligns with the commercial view. Traders Union

The seasonal component layers temporal patterns on top of the COT analysis. Williams pioneered the systematic documentation of repeating seasonal patterns in commodity markets — corn prices typically bottom in late summer at harvest, gold typically rallies in late summer/early fall, etc. The patterns aren't deterministic (they don't work every year), but they produce a baseline expected directional bias that improves the risk-adjusted return of a properly-timed entry. Combined with the COT data and technical timing, the framework produces the kind of multi-factor setup that distinguishes Williams's methodology from purely chart-based technical trading.

Books and the Education Empire

Williams has authored more than a dozen trading books across six decades, including How I Made One Million Dollars Last Year Trading Commodities (1973, his most-cited title), Long-Term Secrets to Short-Term Trading (1999), Sure Thing Commodity Trading (1977), and Trade Stocks & Commodities with the Insiders (2005, the canonical text on COT integration for retail traders). The book volume — likely more than any other actively-trading author in commodity futures — has made Williams's methodology one of the most accessible in serious technical analysis literature. He runs his ongoing education business at IReallyTrade.com and continues to publish his annual market forecast report into the 2020s. Traders Log

The IRS Episode

One piece of difficult history sits in Williams's broader biography. He has been a longtime tax protester — politically opposed to certain elements of U.S. federal income tax policy — and the position eventually produced regulatory action. The IRS pursued Williams on charges of tax evasion related to his trading income, and on February 5, 2010, he pleaded guilty to three misdemeanor charges of failing to file income tax returns on time (for tax years 1999, 2000, and 2001). The three original felony tax evasion charges were dropped as part of the plea agreement; he avoided imprisonment but the episode produced significant legal costs and reputational damage. Williams Investor Profile

Politically, Williams ran twice as a Republican candidate for the U.S. Senate from Montana (1978 and 1982), losing both times in the general election to Democratic incumbents. The political activity is part of why his name remained relatively well-known beyond commodity trading circles — most successful traders aren't also politicians, and the unusual combination has been part of Williams's public identity for decades.

What Traders Can Actually Learn From This

The first lesson from Williams's career is the integration of multiple data sources. Most retail traders use technical indicators alone or fundamental analysis alone; Williams's framework integrates three structurally distinct sources (COT data for institutional positioning, seasonal patterns for temporal bias, technical indicators for entry timing). The combination produces multi-factor setups where the probability of being right on any single trade is higher than what any single factor alone would produce. The implementation isn't easy — it requires actually doing the work of monitoring COT reports, knowing seasonal patterns, and applying technical timing — but the underlying principle (combine multiple uncorrelated edges to produce higher-probability setups) generalizes across all of trading.

The second lesson is the championship-record framing. Williams's 11,376% 1987 return is genuinely extraordinary, but the structural lesson isn't "you can earn 11,000% in a year" — it's that the externally-verified competition framework (Robbins World Cup) produces meaningfully stronger evidence of methodology than self-reported claims. Most retail trading education is sold by people whose track records are either undocumented or carefully curated; Williams's championship win is the kind of audited, externally-administered result that distinguishes legitimate trading expertise from typical guru marketing. The lesson for serious retail traders: weight teachers' records based on the verification standard, not the claimed return.

The third lesson is the systematic teachability of the methodology. The fact that Williams's 16-year-old daughter could win the same championship ten years later — using a version of his methodology she had absorbed through family discussion rather than years of professional development — is partial evidence that the framework is genuinely teachable rather than purely intuitive. Most "successful trader" methodologies don't replicate beyond the original trader; Williams's career produced at least one credible second-generation replication, which is meaningful evidence about the structural transferability of the underlying approach.

Frequently Asked Questions

Disclosure: This article is editorial and contains no affiliate links. Trading involves substantial risk of loss. Larry Williams's 1987 World Cup Championship return of 11,376% is based on broker-audited statements submitted to the championship; the peak intra-year account value has occasionally been questioned because it was reportedly not separately verified through bank statements, though the closing return is fully documented. Individual results vary substantially; Williams's outcomes are not representative of typical commodity trading results, and the specific market conditions of 1987 are not repeatable on demand.
