Comovement Revisited
Chen, Honghui - 2015
Recent evidence of excessive comovement among stocks following index additions (Barberis, Shleifer, and Wurgler, 2005) and stock splits (Green and Hwang, 2009) challenges traditional finance theory. Based on a simple model, we show that the bivariate regressions relied upon in the literature...

Comovement
Barberis, Nicholas - 2002
A number of studies have identifed patterns of positive correlation of returns, or comovement, among different traded securities. We distinguish three views of such comovement. The traditional 'fundamentals' view explains the comovement of securities through positive correlations in the rational...

How the Wealth Was Won : Factors Shares as Market Fundamentals
Greenwald, Daniel - 2019
Why do stocks rise and fall? From the beginning of 1989 to the end of 2017, $34 trillion of real equity wealth (2017:Q4 dollars) was created by the U.S. corporate sector. We estimate that 43% of this increase was attributable to a reallocation of rewards to shareholders in a decelerating...

Regression Discontinuity and the Price Effects of Stock Market Indexing
Chang, Yen-Cheng - 2013
Studies find price increases for additions to the S&P 500 index but no decreases for deletions. Additions come with good earnings news, suggesting these studies are not just measuring an indexing effect. We develop a regression discontinuity design using Russell Indices for cleaner...

Dissecting Characteristics Nonparametrically
Freyberger, Joachim - 2017
We propose a nonparametric method to test which characteristics provide independent information for the cross section of expected returns. We use the adaptive group LASSO to select characteristics and to estimate how they affect expected returns nonparametrically. Our method can handle a large...

Levered Returns
Welch, Ivo - 2016
Do financial markets properly reflect leverage? Unlike Gomes and Schmid (2010) who examine this question with a structural approach (using long-term monthly stock characteristics), my paper examines it with a quasi-experimental approach (using short-term a discrete event). After a firm has...

Estimating the Market-Perceived Monetary Policy Rule
Hamilton, James D. - 2010
We introduce a novel method for estimating a monetary policy rule using macroeconomic news. We estimate directly the policy rule agents use to form their expectations by linking news' effects on forecasts of both economic conditions and monetary policy. Evidence between 1994 and 2007 indicates...

Improving GDP Measurement : a Forecast Combination Perspective
Aruoba, S. Borağan - 2011
Two often-divergent U.S. GDP estimates are available, a widely-used expenditure side version, GDPE, and a much less widely-used income-side version GDPI . We propose and explore a "forecast combination" approach to combining them. We then put the theory to work, producing a superior combined...
