In chapter 8 we discussed optimal risky portfolios. That decision governs how an investor chooses between risk-free assets and “the” optimal portfolio of risky assets. This chapter explains how to construct that optimal risky portfolio. We begin with a discussion of how diversification can reduce the variability of portfolio returns. After establishing this basic point, we examine efficient diversification strategies at the asset allocation and security selection levels. | Lecture Investments 6 e - Chapter 8 Optimal risky portfolios
