“It's all the little important details you learn by repeated study and observation that add to your knowledge and skill and make the difference between succeeding and almost making it in the investment world.”
~ William J. O'Neil

The 1960s that gave birth to the Go-Go Years on Wall Street, was the same time around which a significant cultural shift saw the early success of William J. O'Neil, an outstanding young trader at securities firm Hayden, Stone & Co.

While many investors were relying on P/E ratio as a key stock screening metric, our founder O'Neil studied historical models of winning stocks and developed a proprietary trading methodology that blends quantitative and qualitative analysis-A method we still use today.
