Professor of Finance Avanidhar (Subra) Subrahmanyam (Ph.D. ’90) is an expert in stock market activity and behavioral finance. He is known for his pathbreaking research in the use of psychological principles to explain stock price movements and has published numerous articles in leading peer-reviewed finance and economics journals.
Appearing frequently in the media, Subrahmanyam is consulted for his expertise on the superior performance of value stocks and the phenomenon of stock market momentum to analyze spikes in gasoline prices, herd-like behavior around Apple stock, uncertainty in everyday use of the bitcoin crypto-currency and the effects of war on the stock market.
Subrahmanyam’s current research interests range from the relationship between the trading environment of a firm’s stock and the firm’s cost of capital to behavioral theories for asset price behavior and empirical determinants of the cross-section of equity returns. “We need to accept that humans are governed by a number of non-rational considerations,” he says in relation to investing behaviors. “An investor may be reluctant to admit an erroneous investment decision, which may prevent correction of over-heated stock market valuations. Academic research has indicated to investors that irrational investing can cause a significant loss of wealth.”
A founding editor of the Journal of Financial Markets, Subrahmanyam previously served as associate editor of the Review of Financial Studies and the Journal of Finance. He is a member of the National Bureau of Economic Research’s Working Research Group on Market Microstructure.
His scholarly efforts have been recognized with best paper awards at the Western Finance Association meetings and the International Conference of Finance in Taiwan, and he was honored with the Smith Breeden Prize for the best paper published in the Journal of Finance (1999). His documentation of market liquidity led to a number of studies analyzing why trading costs fluctuate over time and earned him the Fama-DFA prize for the best paper on investments published in the Journal of Financial Economics (2000).
Subrahmanyam has served as a consultant to the Nasdaq Stock Market, the National Stock Exchange in Mumbai, India, San Jose Mercury News and Irwin/McGraw-Hill. He is a UCLA Anderson Inspirational 100 alumnus.
