Firms move between growth and value because of changes in either size or book value of equity. The value premium is specific to variation in book-to-market that emanates from size changes. A factor based on this variation earns the entire value premium; one based on the remaining variation earns no premium. Hence, not all high book-to-market firms earn the value premium, and some low book-to-market firms earn value-like returns. Many models price portfolios sorted by size and book-to-market. None distinguish firms that earn the value premium from those that have a high book-to-market but do not earn the premium.

We use corporate jet flight patterns to identify private meetings with investors that are ex ante unobservable to non-participants. Using approximately 400,000 flights, we proxy for private meetings with “roadshows,” defined as three-day windows that include flights to money centers and to non-money centers in which the firm has high institutional ownership. Roadshows exhibit greater abnormal stock reactions, analyst forecast activity, and absolute changes in local institutional ownership than other flight activity. We also find positive trading gains in firms with more complex information and infrequent private meetings, suggesting that roadshows provide participating investors an advantage over non-participating investors.

Using a dataset of 3,234 letters sent by 434 hedge funds to their investors during 1995–2011, we study what motivates hedge fund managers to make voluntary disclosures. Contrary to the hedge fund industry's reputation for opacity, we observe that managers provide their investors with an array of quantitative and qualitative information about fund returns, risk exposures, holdings, benchmarks, performance attribution, and future prospects. We find that the tensions between the agency costs faced by investors and the proprietary costs faced by managers affect fund disclosures. Consistent with managers reducing proprietary costs, better-performing funds disclose less quantitative data about performance and holdings, and consistent with the presence of agency costs, riskier funds disclose less quantitative information about performance and assets under management.
