It could be concluded that both models provide a BLUE result, meaning to say, both model is efficiently explaining the market phenomena. This demonstrates a weak relationship between dependent variables and independent parameters. This is in sharp contradiction with portfolios that are held by individual shareholders: The Dickey Fuller stationary test was undertaken to determine whether the data was stationary.

From the realization of autoregressive model theory, applying autoregressive analysis as an instrument for estimation of the model would be a potential area of interest for further empirical study.

Second, the market portfolio, M, lies on the efficient frontier and is the tangent asset to the risk-free asset. This would be sufficient to conduct comparison test with this data. As investors, we deserve a rate of return that compensates us for taking on risk.

But does it really work. The linear relationship between beta and individual stock returns also breaks down over shorter periods of time. When professors Eugene Fama and Kenneth French looked at share returns on the New York Stock Exchange, the American Stock Exchange and Nasdaq between andthey found that differences in betas over that lengthy period did not explain the performance of different stocks.

Each individual investor will then choose to allocate his wealth between M and the risk free asset, or in other words the Capital Allocation Line runs between the risk free asset and the portfolio M.

From the theory of the CAPM, the expected positive relationship has now justified with the results. The Formula Sharpe found that the return on an individual stock, or a portfolio of stocks, should equal its cost of capital. Further arrangement is required to fit into FF three factor model.

Nevertheless, the large span of data is favourable to test the theory of capital asset pricing. Consequently, the intercept of the model. Data description The FF three factor model described previously, uses the raw data from varies sources, such that further manipulation is required.

In the result of error term from RHS being distributed independently and identically, the conclusion of homoskedasticity is resulted. Modern portfolio theory shows that specific risk can be removed through diversification.

Under the linear condition of the CAPM, rmrf should be significant to the model; it is evidence from the above table. The CAPM and FF three factor model should not undertake any heteroskedasticity problem, as theory suggests that heteroskedasticity is highly not possible for equity market Peirson, et al, To prepare further study, the concept of elasticity of prices generates new variables to normalise problem that can occur within the model.

Viewed 25th of March,Fama, EF, and. As investors, we deserve a rate of return that compensates us for taking on risk. It is knowledgeable to test for any omitted variable that could affect the model.

Birth of a Model The capital asset pricing model was the work of financial economist and later, Nobel laureate in economics William Sharpe, set out in his book "Portfolio Theory and Capital Markets.

Aim to maximize economic utilities Asset quantities are given and fixed. Eg, subsidiary to companies and sectors Conclusions Overall, the theory contradicts the result from the jointly significance test, it could be concluded that the FF three factor model has the tendency of reverting back to CAPM that it has derived from.

This trade-off between risk and return applies to the CAPM and the efficient frontier graph can be rearranged to illustrate the trade-off for individual assets. Interest rates, recessions and wars are examples of systematic risks.

This is evidenced with the theory of Autoregressive Condition Heteroskedasticity ARCH provides an insight of forecasting probability of following previous trend in equity market is unrealistic Verbeek, Methodology such as taking the elasticity of price and taking the first derivative of elasticity would break down any correlation.

M includes all assets in the economy, with each asset weighted in the portfolio in proportion to its weight in the economy.

Although it is difficult to predict from beta how individual stocks might react to particular movements, investors can probably safely deduce that a portfolio of high-beta stocks will move more than the market in either direction, and a portfolio of low-beta stocks will move less than the market.

The model acted upon the assumption of all investors as risk averse. If so, they can hold low-beta stocks instead. This validates the CAPM, could be a better representation given the current data of deriving the relationship of excess return on portfolio with respect to risk.

From this matrix a portfolio variance and standard deviation could be derived. Not surprisingly, the model has come to dominate modern financial theory. Transformed variables are listed below; Variables Definition dlns1 D1.

The other components of the CAPM formula account for the investor taking on additional risk. The capital asset pricing model is a model that describes the relationship between systematic risk and expected return for assets, particularly stocks.

CAPM is widely used throughout finance for the pricing of risky securities, generating expected returns for assets. Applied Financial Econometrics using Stata 3. Linear Factor Models Stan Hurn Queensland University of Technology.

// estimate CAPM for first portfolio and test alpha = 0 and beta = 1. reg z1 rm_rf Source SS df MS Number of obs = F(1, ) = The analysis of this paper will derive the validity of the Fama and French (FF) model and the efficiency of the Capital Asset Pricing Model (CAPM).

The comparison of the Fama and French Model and CAPM (Sharpe, & Lintner, ) uses real time data of stock market to practise its efficacy. Capital Asset Pricing Model (CAPM) is the backbone of modern portfolio theory.

According to CAPM, the expected return on stock is a function of its relationship with the market portfolio defined by its beta. What is the 'Capital Asset Pricing Model - CAPM' The Capital Asset Pricing Model (CAPM) describes the relationship between systematic risk and expected return for assets, particularly stocks.

CAPM, therefore, evolved as a way to measure this systematic risk. The Formula Sharpe found that the return on an individual stock, or a portfolio of stocks, should equal its cost of capital.
