What William O'Neil and Co does

William O'Neil and Co (William O'Neil + Company, Incorporated) is a privately held, SEC-registered investment adviser founded in 1963 by William J. O'Neil and headquartered in Los Angeles. The firm provides institutional investment research, equity recommendations, and trading services to portfolio managers, hedge funds, pension funds, mutual funds, insurance companies, and corporations. It is controlled by the family holding entity Data Analysis Incorporated, with O'Neil Capital Management serving as the family office.

The core product stack is built on a proprietary stock-picking methodology that blends quantitative and qualitative analysis, supported by a data lake containing more than 100 years of stock market information across 71 developed, emerging, and frontier markets and 70,000+ global equities. Institutional offerings include PANARAY (visual research platform), AlphaScope (equity recommendation algorithm), the Global Focus List, Equity Research, Bespoke Research, Derivatives Research, Global Sector Strategy, IPO Rewind, and the WONDA data feed. Trading execution is delivered through affiliated broker/dealer William O'Neil Securities, which launched the WOSET electronic trading platform in 2026. Retail-facing MarketSmith platforms operate in India and China through wholly-owned subsidiaries.

Revenue is generated through subscription-based institutional research, broker/dealer transaction commissions, systematic strategy fees from O'Neil Global Advisors (e.g., O'Neil Chameleon), and retail subscription products. Distribution is direct enterprise field sales across six offices in the U.S. (Los Angeles, San Francisco, New York, Boston, Chicago) and London, with subsidiaries in India (SEBI-regulated) and China. The firm operates without investment banking, market-making, or proprietary securities positions, and does not currently appear to have external institutional investors or public shareholders.
