| Abstract: | Stock returns are correlated with contemporaneous earnings growth,dividend growth, future real activity, and other cash-flow proxies.The correlation between cash-flow proxies and stock returnsmay arise from association of cash-flow proxies with one-periodexpected returns, cash-flow news, and/or expected-return news.We use Campbell’s (1991) return decomposition to measurethe relative importance of these three effects in regressionsof returns on cash-flow proxies. In some of the popular specifications,variables that are motivated as proxies for cash-flow news alsotrack a nontrivial proportion of one-period expected returnsand expected-return news. As a result, the R2 from a regressionof returns on cash-flow proxies may overstate or understatethe importance of cash-flow news as a source of return variance. |
