O’NEIL Data Systems was founded in 1973 by William J. O’Neil to produce time-sensitive investment research publications from his extensive database on publicly traded companies.
In the mid seventies, O’NEIL pioneered the field of automated composition and database publishing using state-of-the-art computer technology. Since that time, O’NEIL has grown into a national provider of data-driven publishing and marketing communication services for major U.S. organizations.
Mr. O’Neil is one of Wall Street’s most seasoned and successful veterans. At age 30, he bought his own seat on the New York Stock Exchange with profits made in the stock market and founded William O’Neil and Co., Inc., a leading investment research organization. Mr. O’Neil is the founder and publisher of Investor’s Business Daily, one of the world’s leading financial publications. He is also a best selling author of many essential investment books. Mr. O’Neil’s book, How To Make Money In Stocks - A Winning System In Good Times Or Bad, published by McGraw-Hill, is now in its third revised edition.
To date, William J. O’Neil 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. You may also catch him being interviewed on all the major financial news shows on network TV and cable.
