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 = + [()].

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.
Key. ER: Expected return on a specific asset RFR: Risk-free rate, typically the return on a Treasury security Beta: The volatility of the investment MR: The return on a comparable market index To ...
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 ...
The joint hypothesis problem is the problem that testing for market efficiency is difficult, or even impossible. Any attempts to test for market (in)efficiency must involve asset pricing models so that there are expected returns to compare to real returns.
Proposed by economist Stephen Ross in 1976, [1] it is widely believed to be an improved alternative to its predecessor, the capital asset pricing model (CAPM). [2] APT is founded upon the law of one price , which suggests that within an equilibrium market, rational investors will implement arbitrage such that the equilibrium price is eventually ...
