An Intertemporal Capital Asset Pricing Model
Econometrica, 1973Summary: An intertemporal model for the capital market is deduced from the portfolio selection behavior by an arbitrary number of investors who act so as to maximize the expected utility of lifetime consumption and who can trade continuously in time.

A Review of Capital Asset Pricing Models
SSRN Electronic Journal, 2004PurposeThe main aspect of security analysis is its valuation through a relationship between the security return and the associated risk. The purpose of this paper is to review the traditional capital asset pricing model (CAPM) and its variants adopted in empirical investigations of asset pricing.Design/methodology/approachPricing models are discussed ...

There is a great deal of debate in finance literature as to whether Capital Asset Pricing Model is empirically valid, and in particular whether beta can be properly measured. This paper proves that from a theoretical perspective CAPM leads to mathematical contradictions. In other words, CAPM is theoretically invalid, and beta is dead!

This study aims to identify the model of capital asset pricing (CAPM), which occupies a privileged positionin the stock market because it is one of the analysis tools that take into account the relationship betweenreturn and risk in securities and capital investments in general.

Two general approaches to the problem of valuing assets under uncertainty may be distinguished. The first approach relies on arbitrage arguments of one kind or another, while under the second approach equilibrium asset prices are obtained by equating endogenously determined asset demands to asset supplies, which are typically taken as exogenous ...

The Capital Asset Pricing Model
2018The Capital Asset Pricing Model values risky assets. This chapter explores its foundations in diversification and its limits, the calculation of the sensitivity to movements of the market, i.e., beta, combines them into the CAPM, which relates beta as a measure of risk to expected returns, and reconciles it with the continued usage of price-to-earnings

Existence Theorems in the Capital Asset Pricing Model
Econometrica, 1991In the capital asset pricing model (CAPM) a finite number of traders exchange assets, starting with an initial portfolio. Preferences among portfolios of assets are given by a utility function in terms of mean and variance of the returns of the portfolio and characterized by the risk aversion function corresponding to the utility.

The Capital Asset Pricing Model (CAPM) is the most well-known equilibrium model in the capital market. The standard form of CAPM provides a clear description of capital market behaviour if its basic assumptions are respected. There are two main problems. The first one is that some of the basic assumptions are very far from conditions of reality.

New Evidence on the Capital Asset Pricing Model
The Journal of Finance, 1978THE ORIGINAL Sharpe-Lintner capital asset pricing model advanced to explain the variations in risk differentials on different risky assets has now been widely questioned on the basis of the empirical evidence, and a large number of modified theories have been proposed to explain the discrepancies between theory and observation. The evidence points to a

The Capital Asset Pricing Model
2016How can we measure the performance of mutual funds and their investment risk? What is the use of a market index such as S&P 500? The portfolio theory can provide us with the answers. This chapter presents the Capital Asset Pricing Model (CAPM) , which deals with an efficient portfolio management. For a historical introduction see [4].
