Recovering Investor Expectations from Demand for Index Funds

by Mark Egan, Alexander J. MacKay and Hanbin Yang

Abstract

We use a revealed-preference approach to estimate investor expectations of stock market returns. Using data on demand for index funds that follow the S&P 500, we develop and estimate a model of investor choice to flexibly recover the time-varying distribution of expected returns. Despite the fact that they are generated from a different method (realized choices) and a different population, our quarterly estimates of investor expectations are positively and significantly correlated with the leading surveys used to measure stock market expectations. Our estimates suggest that investor expectations are heterogeneous, extrapolative, and persistent. Following a downturn, investors become more pessimistic on average, but there is also an increase in disagreement among participating investors. Our analysis is facilitated by the prevalence of “leveraged” funds, i.e., funds that provide the investor with a menu over leverage. The menu of choices allows us to separately estimate expectations and risk aversion.

Two esports entrepreneurs must choose on which business model to focus their time and money. After successfully launching an online esports coaching platform, a number of new opportunities emerge in the rapidly growing esports space that now has close to one billion gamers and an online audience that is greater than the Superbowl. Should they focus on a B2C business, a B2B business? Develop an analytics capability to support "sabremetrics" for esports or a content creation capability? How can they best exploit ownership of the world's top team in the "Hearthstone" league. The choice will depend on the future industry structure and how the two can most effectively "follow the money."

We study the dynamics of residential electricity demand by exploiting a natural experiment that produced large and long-lasting price changes in over 250 Illinois communities. Using a flexible difference-in-differences matching approach, we estimate that the price elasticity of demand grows from -0.09 in the first six months to -0.27 two years later. We find similar results with a dynamic model in which usage is a function of past and future prices. Our findings highlight the importance of accounting for consumption dynamics when evaluating energy policy.
