This chapter adds realism by magnanimous the investor the opportunity to choose among threefold notional assets. As a University of Chicago graduate student, evoke Markowitz, wrote a path-breaking obligate on this event (Markowitz 1952).1 Markowitzs insight was to tell apart that, in allocating wealth among different bumpy assets, a risk-averse investor should focus on the forethought and the risk of her unite portfolios reverse key, a return that is a?ected by the somebody assets diversi?cation possibilities. Because of diversi?cation, the attractive experience of a particular asset when held in a portfolio derriere di?er from its appeal when it is the resole asset held by an investor. Markowitz proxied the risk of a portfolios return by the pas seul of its return. Of course, the mutation of an investors total portfolio return depends on the return deviations of the case-by-case assets include in the portfolio. But portfolio return variance also depends on the covariances of the individual assets 1 His wager on portfolio theory, of which this article was the beginning, won him a share of the Nobel prize in economic science in 1990. Initially, the sizeableness of his work was not widelyrecognized.

Milton Friedman, a member of Markowitzs doctorial dissertation committee and who also became a Nobel laureate, questioned whether the work met the requirements for an economics Ph.D. See Bernstein (Bernstein 1992). 37 38 CHAPTER 2.
