  2. 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 ...

  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 Rosenberg's model the risk indices X consisted of industry weights and risk indices. Each asset would be given an exposure to one or more industries, e. g. based on breakdowns of the firms balance sheet or earning statement into industry segments. These industry exposures would sum to 1 for each asset.

  5. 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.

  6. 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.

  7. Roll's critique - Wikipedia

    en.wikipedia.org/wiki/Roll's_critique

    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. Modern portfolio theory - Wikipedia

    en.wikipedia.org/wiki/Modern_portfolio_theory

    The CAPM is a model that derives the theoretical required expected return (i.e., discount rate) for an asset in a market, given the risk-free rate available to investors and the risk of the market as a whole. The CAPM is usually expressed:

  9. Low-volatility anomaly - Wikipedia

    en.wikipedia.org/wiki/Low-volatility_anomaly

    The capital asset pricing model (CAPM) predicts a positive and linear relation between the systematic risk exposure of a security (its beta) and its expected future return. However, the low-volatility anomaly falsifies this prediction of the CAPM by showing that higher beta stocks have historically underperformed lower beta stocks. [ 1 ]
