Jack L. Treynor (born February 21, 1930; died May 11, 2016) was noted as one of the discovers, along with William Sharpe, John Lintner, and Jan Mossin, of the Capital Asset Pricing Model (CAPM).[1] Treynor is considered one of the founders of quantitative research analysis.[2] The Treynor ratio is a product of Treynor’s research.[note 1]

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.[2]

In 1962 Treynor produced an unpublished paper, Toward a Theory of the Market Value of Risky Assets, that served as a foundation of the CAPM. Although this paper was circulated among finance economists, it remained unpublished until 1999.[2]

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.[2]

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.[3]

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.[4]
