The Arbitrage Pricing Theory (APT) is due to Ross (1976a, 1976b). It is a one period model in which every investor believes that the stochastic properties of capital assets’ returns are consistent with a factor structure. Ross argues that if equilibrium prices offer no arbitrage opportunities, then the expected returns on these capital assets are approximately linearly related to the factor loadings. (The factor loadings are proportional to the returns’ covariances with the factors.)
