Recent literature (McNulty, Yeh, Schulze, & Lubatkin, 2002) states that the assumptions behind the capital asset pricing model, in particular the irrelevance of time horizon, do not correspond to the characteristics of firms that prefer long-term investment horizons. I show that family firms display a longer time horizon than most of their nonfamily counterparts, since (1) family firms display ...

We investigate the properties of mean-variance efficient portfolios when the number of assets is large. We show analytically and empirically that the proportion of assets held short converges to 50% as the number of assets grows, and the investment proportions are extreme, with several assets held in large positions. The cost of the no-shortselling constraint increases dramatically with the num...

the risk free rate of return plays a main role in financial economic theory and financial markets. due to prohibition of interest in islamic countries there is no specific financial instrument with risk free rate of return as a criterion for measuring the risk free rate of market. we apply the kalman filter to estimate this variable for financial markets in iran. the technique is based on a sta...

The purpose of this study was to examine the expected returns of Carhart model compared to the capital asset pricing model and the implicit capital cost model based on cash and capital returns of growth and value stocks. The statistical population consisted of the companies listed in Tehran Stock Exchange and the time domain is between 2007 and 2016. By choosing Cochran sampling, 126 companies ...

Futures on fresh farmed salmon traded at the Fish Pool market in Norway are analyzed context of Capital Asset Pricing Model (CAPM) and a corresponding three-factor model where contracts separated based their maturities. Looking into 1 month; 6 months 12 contracts, we find that all alphas most betas statistically insignificant. We conclude CAPM equilibrium condition holds Salmon futures prices m...

This paper re-examines the tests of the Sharpe-Lintner Capital Asset Pricing Model (CAPM). The null that the CAPM intercepts are zero is tested for ten size-based stock portfolios and for twenty five book-to-market sorted portfolios using five-year, ten-year and longer sub-periods during 1965-2004. The paper shows that the evidence for rejecting the CAPM on statistical grounds is weaker than th...

Article history: Received 18 November 2010 Accepted 12 September 2011 Available online 17 September 2011 This paper evaluates and compares asset pricing models in the Korean stock market. The asset pricing models considered are the CAPM, APT-motivated models, the Consumption-based CAPM, Intertemporal CAPM-motivated models, and the Jagannathan and Wang conditional CAPM model. By using various te...

The Sharpe (1964), Lintner (1965) and Black (1972) Capital Asset Pricing Model (CAPM) is considered one of the foundational contributions to the practice of finance. The model postulates that the equilibrium rates of return on all risky assets are a linear function of their covariance with the market portfolio. Recent work by Fama and French (1996, 2006) introduce a Three Factor Model that ques...

modern portfolio theories are based on markowitz’s portfolio optimization model that involves the assumption of mean variance behavior and therefore require the asymmetry and normality of returns. this issue also affects the capital asset pricing model that estimates systematic risk and uses it in pricing securities. this article analyzes the various measures of risk. the main purpose of this r...
