The market consists of only two assets, A and B, with normally distributed re- turns. Asset A's returns have a mean of 18% and a standard deviation of 14% and Asset B's returns have a mean of 15% and a standard deviation of 18%. In such a scenario a risk-averse investor would always want to invest all of her money in Asset A. 17.

The market portfolio of all available assets is the supply of risky assets. 22. An arbitrage opportunity is an investment strategy yielding strictly negative net gain today and no loss in any state of the world in the future. 23.
