In 2001, O’Shaughnessy and his team from O’Shaughnessy Capital Management moved to Bear Stearns Asset Management (BSAM), where O’Shaughnessy served as a Senior Managing Director and the executive director of Systematic Equity. In 2007, O’Shaughnessy reached an agreement with Bear Stearns to spin his Systematic team out of BSAM to form O’Shaughnessy Asset Management, LLC.

In 1999, O'Shaughnessy started Netfolio, The Personal Fund Company, to offer individual investors the ability to build their own diversified portfolio over the internet. The company was closed in 2001. As part of Netfolio's concentration on “personal funds” O’Shaughnessy Capital Management sold their mutual fund family to Hennessy Advisors in June 2000.

In 1997, the Royal Bank of Canada (RBC) launched the RBC O'Shaughnessy mutual funds for Canadian investors. Currently, there are seven mutual funds in the RBC O’Shaughnessy funds family.

O'Shaughnessy started his own mutual funds under the names Cornerstone Growth and Cornerstone Value in 1996.

O'Shaughnessy continued to apply his research of the stock market and, in 1994, his first book Invest Like the Best was published, followed by the first edition of What Works on Wall Street in 1997, How to Retire Rich in 1998, and Predicting the Markets of Tomorrow in 2006.

In 1991, O'Shaughnessy moved his family to Greenwich, Connecticut, to be closer to the New York area, where most of his business was located.

After graduating, O'Shaughnessy worked for a family-owned venture capital firm. During this time, his interest in quantitative research was recognized by a colleague who was on the board of directors with O'Shaughnessy at the St. Paul Chamber Orchestra. The colleague suggested that O'Shaughnessy's research might be well suited for pension plan management. In 1988, O'Shaughnessy started O'Shaughnessy Capital Management, Inc. and began consulting to large pension funds and foundations.
