The major assumptions of APT (arbitrage pricing theory) are (3)
The major assumptions of APT (arbitrage pricing theory) are as follows: asset returns are described by a factor model; there are many assets, so asset-specific risk can be eliminated (not factor risk); assets are priced such that there are no arbitrage opportunities
Fundamental Factor Models
Fundamental Factor Models – factors are attributes of stocks or companies
Statistical Factor Models
Statistical Factor Models – statistical methods are applied to a set of historical returns
Arbitrage Opportunity (portfolio/model)
Arbitrage Opportunity: compare given expected returns to model expected returns, long or short the portfolio with the inequality, then buy or sell (opposite of arbitrage portfolio) and combination of the equality portfolios using weights to match the arbitrage portfolio qualities
Value Added
Value Added – related to active weights in the portfolio, defined as differences between the various asset weights in the managed portfolio and their weights in the benchmark portfolio
Information Ratio
Information Ratio: IR=(R_P-R_B)/(STD(R_P-R_B))=R_A/(STD(R_A))=(Active Return)/(Active Risk)
Expected Active Return
Expected Active Return: E(R_A )=(TC)(IC)√BR σ_A where IR=IC√BR where TC – transfer coefficient, IC – information coefficient, BR – breadth (# independent decisions per year), σA – active risk, IR – information ratio
