This study documents the asset pricing mechanism of Sharīʿah compliant securities listed on the Karachi Stock Exchange. We select the CAPM market model to test for the impact in variations of stock returns on a sample of Sharīʿah-compliant companies on ten years monthly data (2001-10). We first test the basic CAPM (Capital Asset Pricing Model) and its modified form known as the Sharīʿah-complia...

We propose an errors-in-variables factor model which extends the classical capital asset pricing model (CAPM) to the case where the market returns contain additive noise. Using the model, we propose a method for choosing portfolios of assets, such as U.S. stocks in the S&P 100 and virtual electricity contracts in a regional transmission organization. Virtual electricity contracts relate real-ti...

This paper derives a dynamic version of the international CAPM. The exchange-rate risk factors and intertemporal hedging factors are derived endogenously in a model that builds upon Campbell (1993). We provide a theoretical foundation for empirical risk factors often used in international asset pricing, including dividend yields, forward premia and, especially, exchange-rate indices. The model ...

longer follow. The capital asset pricing model (CAPM) is an elegant theory. With the aid of some simplifying assumptions, it comes to dramatic conclusions about practical matters, such as how to choose an investment portfolio, how to forecast the expected return of a security or asset class, how to price a new security, or how to price risky assets in a merger or acquisition. The CAPM starts wi...

One of the bedrocks of modern capital market theory is that market risk and related statistics are stable over the long run. Nobel prizes have been won for this insight, and it is taught in the best business schools. Regulations have also been written based upon this assumption. Yet, experience does not support this idea. We know that often markets have periods of relative stability, but they c...

We study the impact of delegated portfolio management on asset pricing in a large-scale experimental setting. As predicted by standard models, in early rounds of our experiments delegation has no impact on pricing; we replicate CAPM pricing as in earlier experiments without delegation. However, CAPM pricing fails in later rounds. We attribute this to the fund flows: investors tend to increase a...

This article provides an empirical investigation into the validity of the production-based capital asset-pricing model (P-CAPM) in the Japanese asset markets during the period 1980-1997. Several methodologies are used to test the P-CAPM, which include the GMM test of the Euler equations, the volatility bound test, the mispricing test, and the test of the ability of stock and investment returns ...
