William J. O’Neil: Revolutionizing Finance Through CAN SLIM and Investor’s Business Daily

William J. O’Neil’s journey begins in Oklahoma City on March 25, 1933, against the backdrop of the Great Depression and the Dust Bowl. Influenced by the financial challenges of his early years, O’neil pursued a business degree at Southern Methodist University, earning his bachelor’s degree in 1955.

In 1958, O’neil commenced his career as a stockbroker with Hayden, Stone, & Co. in Los Angeles. Recognizing the transformative potential of data analytics in the realm of investments, he founded William O’Neil Co. Inc. in 1963. This pivotal move led to the development of the first computerized daily securities database, a groundbreaking innovation that tracked over 70,000 companies globally. At the age of 30, O’neil achieved another milestone by becoming the youngest person to secure a seat on the prestigious New York Stock Exchange (NYSE).

O’neil’s revolutionary contribution to investment strategies is epitomized by the CAN SLIM strategy, a meticulous formula incorporating technical and fundamental analyses. This acronym encompasses seven essential traits for evaluating a company’s growth potential:
C: Current quarterly earnings: Assessing a company’s recent earnings to gauge financial health.
A: Annual earnings: Examining a company’s yearly earnings for consistent profitability.
N: New positive changes: Identifying positive changes within a company that may contribute to growth.
S: Supply and demand: Analyzing the supply of shares available in the market.
L: Leadership in the industry: Evaluating the company’s leadership role within its industry.
I: Institutional sponsorship: Gauging the level of investment from large financial institutions.
M: Market direction: Assessing the company’s ability to align with broader market trends.

This compilation of charts provided individual investors with the same high-quality research tools employed by institutional investors. Known for their clarity and design, these charts became immensely popular.
The evolution continued with the launch of MarketSmith in 2010, representing the next generation of Daily Graphs Online investment research service. MarketSmith, based on fundamental and technical analyses, incorporates O’neil’s seven fundamental factors that repeatedly surface in top-performing companies over various market cycles.

In 1984, O’neil established Investor’s Daily, a national business newspaper that would later be rebranded as Investor’s Business Daily in 1991. The publication quickly gained prominence for providing unique investor tools, research, and analytical products. In 2021, News Corp’s announcement of acquiring Investor’s Business Daily further underscored its enduring significance.
As of 2023, Investor’s Business Daily’s website attracts more than 5.2 million unique visitors per month. The platform continues to be a vital resource for investors seeking comprehensive financial insights.
