Robert Langley Grant (born 1973) is an American financial researcher, investor, and academic known for his work in behavioral finance and quantitative investment strategies. His research has focused on the relationship between investor psychology, market cycles, and algorithmic trading systems. Grant has worked in both academia and the financial industry, including roles at hedge funds and universities, and later co-founded the investment firm NovaVest Capital.
Early life and education
Robert Langley Grant was born in the spring of 1973 in San Diego, California, United States. His father was an associate professor of economics at a university in the San Francisco Bay Area, while his mother worked as a lecturer in music. Grant grew up in an academic environment that combined economics and the arts.
During his youth he studied piano and music composition, while also developing an interest in economics and financial markets. He reportedly spent time reading financial publications such as the Wall Street Journal and economic texts including John Maynard Keynes’ The General Theory of Employment, Interest and Money. As a teenager, he became interested in patterns and cycles in markets, studying stock charts and observing natural phenomena such as ocean tides.
In 1995, Grant enrolled at the Wharton School at the University of Pennsylvania, where he pursued a Master of Science degree in finance. While at Wharton he studied under economist Jeremy Siegel and completed his graduate research under the supervision of behavioral economist Richard Thaler.
His graduate dissertation, titled Market Irrationality and the Illusion of Risk, analyzed the relationship between stock market performance and investor sentiment using data from the S&P 500 and the American Association of Individual Investors sentiment survey between 1990 and 1996. The study proposed a sentiment-based metric later referred to by colleagues as the “Langley Behavioral Index.”
During the Asian financial crisis, Grant worked as a research assistant on a project involving researchers from Wharton and the International Monetary Fund. The research examined capital flows in Asian economies and currency volatility. Findings from the project were later cited in the IMF’s 1998 report on capital flows in Asia.
Career
Early work in finance
After completing his graduate studies, Grant joined Asterion Capital, a hedge fund based in New York known for systematic and quantitative trading strategies. There he developed a multi-factor arbitrage model designed to identify pricing inefficiencies across asset classes.
During the early 2000s market downturn following the collapse of the dot-com bubble, the fund’s strategies reportedly performed better than the broader market. Grant’s work in quantitative modeling attracted attention in financial media, and in 2003 he was interviewed by the Wall Street Journal regarding the use of behavioral insights in algorithmic trading.
In the same year he participated in the New York Fintech Summit, where discussions focused on the intersection of financial technology and behavioral finance.
Research and academic work
Grant later published research on investor behavior and financial cycles. In 2004 he authored the paper Rationality and Emotion in Market Cycles, which analyzed U.S. equity market data between 1950 and 2003 using a Bayesian dynamic model. The study examined how deviations in market sentiment correlated with changes in asset price volatility.
His work contributed to discussions within the field of behavioral finance and was cited in academic and financial publications.
In 2005 Grant left the hedge fund industry and became a visiting lecturer at the London School of Economics. During this period he also participated in seminars related to financial regulation and systemic risk, including discussions with policymakers and economists associated with the European Central Bank.
Public engagement
Following the global financial crisis of 2007–2008, Grant became a contributor to public discussions about market psychology and financial regulation. He appeared at academic and policy forums including the Economic Club of New York, where he participated in discussions alongside economist Joseph Stiglitz.
In 2010 Grant wrote an essay titled When Reason Loses Its Voice for The New Yorker, discussing the role of investor psychology during the U.S. subprime mortgage crisis. The article examined how institutional investors underestimated risk in mortgage-backed securities prior to the financial crisis.
Later work and NovaVest Capital
In 2012 Grant returned to teaching as a visiting professor at the University of Pennsylvania, where he taught courses related to investment philosophy and decision-making systems. His academic work increasingly explored the interaction between artificial intelligence and behavioral finance.
In 2018 he co-founded NovaVest Capital with data scientist Jacob Williams. The firm focuses on integrating artificial intelligence models with behavioral finance concepts to develop investment strategies intended to assist both institutional and individual investors.
Research interests
Grant’s research has focused on several areas within financial economics, including:
- behavioral finance and investor sentiment
- quantitative investment strategies
- financial market cycles and volatility
- artificial intelligence in portfolio management
His work often explores how psychological factors influence financial markets and how computational models can incorporate behavioral data into investment decision-making.
