In finance, arbitrage pricing theory (APT) is a multi-factor model for asset pricing which relates various macro-economic (systematic) risk variables to the pricing of financial assets. 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 ...
Ross is best known for the development of the arbitrage pricing theory (mid-1970s) as well as for his role in developing the binomial options pricing model (1979; also known as the Cox–Ross–Rubinstein model). He was an initiator of the fundamental financial concept of risk-neutral pricing.
In a discrete (i.e. finite state) market, the following hold: [2] The First Fundamental Theorem of Asset Pricing: A discrete market on a discrete probability space (,,) is arbitrage-free if, and only if, there exists at least one risk neutral probability measure that is equivalent to the original probability measure, P.
The arbitrage pricing theory (APT), a general theory of asset pricing, has become influential in the pricing of shares. APT holds that the expected return of a financial asset can be modelled as a linear function of various macro-economic factors, where sensitivity to changes in each factor is represented by a factor specific beta coefficient:

Investment theory, which is near synonymous, encompasses the body of knowledge used to support the decision-making process of choosing investments, [4] [5] and the asset pricing models are then applied in determining the asset-specific required rate of return on the investment in question.
