  2. Factor theory - Wikipedia

    en.wikipedia.org/wiki/Factor_theory

    The original factor model is the capital asset pricing model (CAPM), which predicts that an asset's expected return in excess of the risk-free rate is wholly determined by its exposure to the market factor. More formally, an asset's expected excess return is linearly related its co-movement with the market portfolio.

  3. Capital asset pricing model - Wikipedia

    en.wikipedia.org/wiki/Capital_asset_pricing_model

    An estimation of the CAPM and the security market line (purple) for the Dow Jones Industrial Average over 3 years for monthly data.. In finance, the capital asset pricing model (CAPM) is a model used to determine a theoretically appropriate required rate of return of an asset, to make decisions about adding assets to a well-diversified portfolio.

  4. Multiple factor models - Wikipedia

    en.wikipedia.org/wiki/Multiple_factor_models

    In mathematical finance, multiple factor models are asset pricing models that can be used to estimate the discount rate for the valuation of financial assets; they may in turn be used to manage portfolio risk.

  5. Consumption-based capital asset pricing model - Wikipedia

    en.wikipedia.org/wiki/Consumption-based_capital...

    The CAPM can be derived from the following special cases of the CCAPM: (1) a two-period model with quadratic utility, (2) two-periods, exponential utility, and normally-distributed returns, (3) infinite-periods, quadratic utility, and stochastic independence across time, (4) infinite periods and log utility, and (5) a first-order approximation ...

    Roll's critique is a famous analysis of the validity of empirical tests of the capital asset pricing model (CAPM) by Richard Roll. It concerns methods to formally test the statement of the CAPM, the equation = + [()].

  8. Fama–MacBeth regression - Wikipedia

    en.wikipedia.org/wiki/Fama–MacBeth_regression

    The Fama–MacBeth regression is a method used to estimate parameters for asset pricing models such as the capital asset pricing model (CAPM). The method estimates the betas and risk premia for any risk factors that are expected to determine asset prices.

  9. Jensen's alpha - Wikipedia

    en.wikipedia.org/wiki/Jensen's_alpha

    We obtain the CAPM alpha if we consider excess market returns as the only factor. If we add in the Fama-French factors (of size and value), we obtain the 3-factor alpha. If additional factors were to be added (such as momentum) one could ascertain a 4-factor alpha, and so on. If Jensen's alpha is significant and positive, then the strategy ...
