Career
Treynor was born on February 21, 1930 in Council Bluffs, Iowa. He received a bachelor's degree in math from Haverford College, Pennsylvania, in 1951. After serving in the US Army for two years, Treynor received an MBA from Harvard Business School in 1955.

In 1962 Treynor produced an unpublished paper, Toward a Theory of the Market Value of Risky Assets, that served as a foundation of the CAPM. Although this paper was circulated among finance economists, it remained unpublished until 1999.

Treynor’s employment history included a stint with the consulting firm Arthur D. Little Inc. and a later (1966 to 1969) position at Merrill Lynch, where he was tasked with creating a quantitative research group. Treynor then became editor (1969 to 1980) of the Chartered Financial Analysts Journal.

Treynor was conferred with the 1997 James Vertin award, presented periodically to recognize individuals who have produced a body of research notable for its relevance and enduring value to investment professionals.

In 2014 the Q group introduced the Treynor Prize to recognize superior academic working papers with potential applications in the fields of investment management and financial markets.
