independent variables in a regression analysis; for instance, the percentage of variation in the return of an
asset explained by the market portfolio return.

Market model

This relationship is sometimes called the single-index model. The market model says that the
return on a security depends on the return on the market portfolio and the extent of the security's
responsiveness as measured, by beta. In addition, the return will also depend on conditions that are unique to
the firm. Graphically, the market model can be depicted as a line fitted to a plot of asset returns against
returns on the market portfolio.

Efficient Market Hypothesis

In general the hypothesis states that all relevant information is fully and
immediately reflected in a security's market price thereby assuming that an investor will obtain an equilibrium
rate of return. In other words, an investor should not expect to earn an abnormal return (above the market
return) through either technical analysis or fundamental analysis. Three forms of efficient market hypothesis
exist: weak form (stock prices reflect all information of past prices), semi-strong form (stock prices reflect all
publicly available information) and strong form (stock prices reflect all relevant information including insider
information).

Efficient portfolio

A portfolio that provides the greatest expected return for a given level of risk (i.e. standard

Equilibrium market price of risk

unit change in risk.
