We test whether the country risk variable is a significant risk factor in several CAPM based models of expected equity returns in Argentina, Brazil, Mexico, South Africa, Russia, Turkey and Venezuela. We also test the usual assumption that country risk can be added with a coefficient value of...

Although portfolio management didn’t change much during the 40 years after the seminal works of Markowitz and Sharpe, the development of risk budgeting techniques marked an important milestone in the deepening of the relationship between risk and asset management. Risk parity then became a...

In this paper, we investigate whether the international version of CAPM can price rational and irrational sentiments of U.S. individual and institutional investor sentiments. The results show that the CAPM prices rational sentiments driven by fundamentals and irrational sentiments not driven by...

This note develops the solutions of the static portfolio optimization problem in explicit matrix form. Three cases are contemplated and connected, with the derivation of relevant corner solutions: the unconstrained problem in the presence of risky assets only, the constrained one, and the...

We analyze the stock prices of the S&P market from 1987 to 2012 with the covariance matrix of the firm returns determined in time windows of several years. The eigenvector belonging to the leading eigenvalue (market) exhibits in its long term time dependence a phase transition with an order...

Under a comonotonicity assumption between aggregate dividends and the market portfolio, the CCAPM formula becomes more tractable and more easily testable. In this paper, we provide theoretical justifications for such an assumption.

It is well-known that cross-sectional tests of the CAPM are problematic. The market indexes used in empirical tests are likely to be inefficient ex ante, which could lead to spurious results even in the absence of sampling errors. This problem has led many to express serious doubt on the...

Using a new dataset for the German market, this article analyses whether modeling time-varying stochastic discount factor parameters in the CAPM of Sharpe (1964), the HCAPM of Jagannathan and Wang (1996) and the CCAPM of Lucas (1978) can help to explain the cross-section of book-to-market, size...

Robust estimation techniques based on symmetric probability distributions are often substituted for OLS to obtain efficient regression parameters with thick-tail distributed data. The empirical, simulation and theoretical results in this paper show that with skewed distributed data, symmetric...

This article proposes an alternative approach to estimating the required rate of return on equity, combining the bond-plus risk-premium approach and the Capital Asset Pricing Model, and tests it using Canadian data. Individual stock risk-premia are classified into groups according to the point...
