Measures of short sale constraints and short selling activity strongly predict stock returns. This apparently exploitable predictability is difficult to explain. We partially resolve this puzzle by using measures of the stock borrowing costs paid by short-sellers. We show in portfolio sorts that the returns to short selling, net of stock borrowing costs, are much smaller than the gross returns to shorting or a typical long-short strategy. Option-implied borrowing fees, which reflect option market makers’ borrowing costs and the risks of changes in those costs, are on average only slightly higher than quoted borrowing fees. This finding indicates that the risk of changes in borrowing fee does not command a substantial risk premium. Option-implied borrowing fees predict future fees and stock returns, including returns net of quoted borrowing costs. The option-implied fee drives out other return predictors in panel regressions including option-based variables and other measures of short selling activity.


Dmitriy Muravyev is an assistant professor of finance at Boston College’s Carroll School of Management. His research focuses on using derivative securities to answer important questions in financial economics. His recent research projects study the determinants of risk-premium and trading costs in the options market, information flows between options and the underlying stocks. His research has been published in the Journal of Financial Economics and the Journal of Finance. Professor Muravyev received his Ph.D. in Finance from the University of Illinois at Urbana-Champaign. He also holds an M.Sc. in applied mathematics from Moscow State University and an M.A. in economics from the New Economic School, Moscow.

IAQF-Thalesians Seminars

The IAQF-Thalesians Seminar Series is a joint effort on the part of the IAQF and the Thalesians. The goal of the series is to provide a forum for the exchange of new ideas and results related to the field of quantitative finance. This goal is accomplished by hosting seminars where leading practitioners and academics present new work, and following the seminars with a reception to facilitate further interaction and discussion. The seminar series is limited to IAQF and Thalesians members only.
