In this study we investigate the valuation implications of managerial actions undertaken by 57 Internet firms engaged in Business-to-Business (B2B) e-commerce.
We examine the valuation performance of a comprehensive list of value drivers and find that multiples derived from forward earnings explain stock prices remarkably well: pricing errors are within 15 percent of stock prices for about half our sample. In terms of relative performance, the following general rankings are observed consistently each year: forward earnings measures are followed by historical earnings measures, cash flow measures and book value of equity are tied for third, and sales performs the worst.
This paper studies the economic benefits of return predictability by analyzing the impact of market and volatility timing on the performance of optimal portfolio rules. Using a model with time-varying expected returns and volatility, we form optimal portfolios sequentially and generate out-of-sample portfolio returns. We are careful to account for estimation risk and parameter learning.
The financial press and accounting regulators (e.g., the Securities and Exchange Commission and Financial Accounting Standards Board) have expressed concern about pressures on Internet firms to report high levels of revenue. This study verifies the association between market capitalization and revenue, and examines economic factors that potentially influence Internet company managers' decisions to adopt allegedly aggressive revenue-recognition policies. Specifically, we examine factors hypothesized to influence the reporting of advertising barter revenue and grossed-up sales levels.
Articles in the financial press suggest that institutional investors are overly focused on current profitability, which suggests that as institutional ownership increases, stock prices reflect less current period information that is predictive of future period earnings. On the other hand, institutional investors are often characterized in academic research as sophisticated investors and sophisticated investors should be better able to use current-period information to predict future earnings compared with other owners.
We examine whether executive stock options (ESOs) provide managers with incentives to invest in risky projects. For a sample of oil and gas producers, we examine whether the coefficient of variation of future cash flows from exploration activity (our proxy for exploration risk) increases with the sensitivity of the value of the CEO's options to stock return volatility (ESO risk incentives). Both ESO risk incentives and exploration risk are treated as endogenous variables by adopting a simultaneous equations approach.
We investigate the relation between dividend changes and future profitability, measured in terms of either future earnings or future abnormal earnings. Supporting "the information content of dividends hypothesis," we find that dividend changes provide information about the level of profitability in subsequent years, incremental to market and accounting data. We also document that dividend changes are positively related to earnings changes in each of the two years after the dividend change.
Did analysts contribute to perpetuating the stock market bubble of 2000? In my view, a considerable analysis during the bubble was suspect. I lay out here what I see as the mistakes, as a matter of historical record. My aim, however, is not just to document the poor thinking during the bubble, but to convey what good, orderly thinking about fundamental value involves—to avoid mistakes in the future.
