William O'Neil founded the CANSLIM method of trading
Born in Oklahoma and raised in Texas, William O'Neil began his career as a stockbroker with Hayden, Stone & Company where he started to formulate his comprehensive investment strategies. His fascination with the securities market led him to develop his own computerized study of what makes a stock successful. This study was adapted and published as The Model Book Of Greatest Stock Market Winners, and was the basis for his CAN SLIM™ discipline.
After a 20-fold increase in his own account in 26 months, Mr. O'Neil bought a seat on the New York Stock Exchange and formed William O'Neil + Co. Inc. in 1963. Since then, the CAN SLIM™ discipline led to the development of many important investment research tools.
Realizing the need to deliver his time-sensitive research publications ahead of the competition, in 1973 Mr. O'Neil founded O'Neil Data Systems, Inc. In addition to providing high-speed printing facilities, ODS pioneered the field of database publishing using state-of-the-art computer technology. Today, ODS specializes in producing time-sensitive publications for many companies in a variety of fields. It is listed as one of Printing Impressions' top 500 companies in the United States.
In 1984 William O'Neil designed and launched Investor's Business Daily®, the first national business newspaper to compete successfully with, and gain market share from, the 100-year old industry legend, The Wall Street Journal. In a modern-day David and Goliath story, Mr. O'Neil used his years of experience in economic and business research and his massive historical database to fill a daily information gap that existed for the individual investor and business community.
Mr. O'Neil's latest book, How To Make Money In Stocks - A Winning System In Good Times Or Bad, published by McGraw-Hill and now in its third revised edition, was the best-selling investment book of 1988. Mr O'Neil is also the author of the bestseller 24 Essential Lessons For Investment Success .
To date, he continues to conduct lectures across the country to sold-out audiences of institutional and individual investors on his strategies for identifying winning stocks and minimizing losses.
