Portfolio Diversification and Supporting Financial Institutions

In this lecture, Professor Shiller introduces mean-variance portfolio analysis, as originally outlined by Harry Markowitz, and the capital asset pricing model (CAPM) that has been the cornerstone of modern financial theory. Professor Shiller commences with the history of the first publicly traded company, The United East India Company, founded in 1602. Incorporating also the more

A diversification benefit exists when a portfolio’s standard deviation can be reduced without reducing expected return. The diversification benefit is possible when return correlations between portfolio assets is less than perfect positive correlation (<+1.0). If assets have less than a +1.0 correlation, then some of the random fluctuation around the expected trend rates of return

Mean-Variance Analysis Assumptions

Mean-variance analysis gives investors a framework to assess the tradeoff between risk and return as mean-variance analysis quantifies the relationship between expected return and portfolio variance (or standard deviation). Mean-variance analysis is the theoretical foundation of Modern Portfolio Theory established by Professor Harry Markowitz and much of the material covered in this module traces its

Real Estate Portfolios

Measuring the income from a property is easy but assessing appreciation

Immunization Against Non-parallel Shifts

One of the assumptions of the classical immunization theory is that if the interest rates change, the same changes by same quantum across all periods of maturities of bonds. However, at many a occasions, the change in interest rates may not be uniform across all the periods of bond maturities. Thus, equating the duration of
