Which of the following statements are true of the arbitrage pricing theory? More than one answer may be correct. Multiple select question. It shows that the expected return on any risky asset is a linear combination of various factors. It can handle multiple factors that the capital asset pricing model (CAPM) ignores. It is based on the assumption that all securities have zero systematic risk. It is based on the assumption that there are plenty of arbitraging opportunities in the market.

How does the Arbitrage Pricing Theory (APT) differ from and complement the Capital Asset Pricing Model (CAPM)? The Arbitrage Pricing Theory, developed by Stephen Ross, proposes that an asset's returns can be predicted using the linear relationship between the asset's expected return and a number of macroeconomic factors. Unlike CAPM, which uses a single factor (market risk), APT allows for multiple factors to explain asset returns, potentially providing a more comprehensive risk-return framework. These factors might include inflation, GDP growth, interest rates, or market indices. APT is based on the principle that arbitrage opportunities will be eliminated in efficient markets, leading to a pricing equilibrium. While more flexible than CAPM, APT faces challenges in identifying and measuring relevant factors. The theory has important implications for portfolio management, asset valuation, and our understanding of risk premiums in financial markets.

Which of the following is not a characteristic of an efficient market? Investors can frequently make profits by predicting asset market prices that are different from intrinsic values. The market value of all securities at any one instant in time fully reflect all available information. Investors act rationally. The forces of demand and supply work to maintain that the security's market price and its intrinsic value are in equilibrium.

In contrast to the capital asset pricing model, arbitrage pricing theory:a. Requires that markets be in equilibrium.b. Uses risk premiums based on micro variables.c. Specifies the number and identifies specific factors that determine expected returns.d. Does not require the restrictive assumptions concerning the market portfolio.
