William J. O'Neil (born March 25, 1933) is an American entrepreneur, stockbroker and writer, who founded the stock brokerage firm William O'Neil & Co. Inc in 1963 and the business newspaper Investor's Business Daily in 1983. He is the author of the books How to Make Money in Stocks, 24 Essential Lessons for Investment Success and The Successful Investor among others, and is the creator of the CAN SLIM investment strategy.
O'Neil was born March 25, 1933 in Oklahoma City and raised in Texas. In 1951, he graduated from Woodrow Wilson High School in Dallas, Texas. He studied business at Southern Methodist University, received a bachelor's degree in 1955 and served in the United States Air Force.
In 1958, O'Neil started his career as a stockbroker at Hayden, Stone & Company, and developed an investment strategy which made early use of computers. In 1960, he was accepted to Harvard Business School's first Program for Management Development (PMD). From his research, O'Neil invented the CAN SLIM strategy and became the top-performing broker in his firm. He bought a seat on the NYSE at age 30 and became the youngest at that time ever to do so. In 1963, he founded William O'Neil + Co. Inc., a company which developed the first computerized daily securities database and sold its research to institutional investors and tracks over 70,000 companies worldwide.
Daily Graphs was launched by William O'Neil to produce Daily Graphs, a printed book of stock charts delivered weekly to subscribers in 1972. In 1998, O'Neil launched Daily Graphs Online as a comprehensive online equity research tool and an extension of the Daily Graphs business he launched in 1972. In 2010, Daily Graphs Inc. and its service was re-branded as MarketSmith.
In 1973, he founded "O'Neil Data Systems, Inc.", to provide high-speed printing and database-publishing facilities. The company now operates as O'Neil Digital Solutions and has operations in Los Angeles, Dallas and Monroe, North Carolina. The firm provides data-driven publishing and marketing communications.
