Using a CCAPM based risk adjustment model, consistent with general asset pricing theory, I perform corporate valuations of a large sample of stocks listed on NYSE, AMEX and NASDAQ. The model is different from the standard CAPM model in the sense that it discounts forecasted residual income for...

This article analyzes the manifold situations in which the efficient-market hypothesis (EMH) has influenced—or has failed to influence—federal securities regulation and state corporate law, and the prospective roles for the EMH in these contexts. In federal securities regulation, the EMH has...

A key result of the Capital Asset Pricing Model (CAPM) is that the market portfolio---the portfolio of all assets in which each asset's weight is proportional to its total market capitalization---lies on the mean-variance efficient frontier, the set of portfolios having mean-variance...

Building on neoclassical reasoning, we propose a new multi-factor model that consists of the market factor and factor mimicking portfolios based on investment and productivity. The neo- classical three-factor model outperforms traditional factor models in explaining the average returns across...

During the week of August 6, 2007, a number of quantitative long/short equity hedge funds experienced unprecedented losses. It has been hypothesized that a coordinated deleveraging of similarly constructed portfolios caused this temporary dislocation in the market. Using the simulated returns of...

In this paper we study the intraday price formation process of country Exchange Traded Funds (ETFs). We identify specific parts of the US trading day during which Net Asset Values (NAVs), currency rates, premiums and discounts, and the S&P 500 index have special effects on ETF prices, and...

We examine the performance of the buy-write option strategy (BWS) on the Australian Stock Exchange and analyse whether such an investment opportunity violates the efficient market hypothesis on the basis of its risk and returns. This study investigates the relationship between buy-write...

We compare the investment technology of foreign versus domestic investors with a focus on decomposing outcomes attributable to asset allocation and security selection. We document significant differences in exposure to systematic asset pricing factors between foreign and domestic investors. A...

In this paper, we analyze whether the state of the limit order book affects future price movements in line with what recent theoretical models predict. We do this in a linear vector autoregressive system which includes midquote return, trade direction and variables that are theoretically...

Es una práctica muy difundida el multiplicar la desviación estándar por la raíz del tiempo para escalarla a otros plazos. Así, con base en la estimación de la desviación estándar o del VaR (Value at Risk) diario, es usual obtener la desviación estándar o el VaR para un periodo de diez...
