Abstract
How should we invest our wealth? Portfolio theory is based upon two principles:1
-
We want to maximize the expected return; and
-
We want to minimize the risk which we define in this chapter to be the standard deviation of the return, though we are ultimately concerned with the probabilities of large losses.
