CAPM came under a lot of scrutiny and attack as its simplicity also led to extensive testing which did not bear out the conclusions. This paper seeks to re-think CAPM in light of the broader trend in the institutional world to implement Liability Driven Investments (LDI) to see if this can help...

There is an annuity puzzle in that the actual allocation by individuals to annuities is low. Longevity bonds, to hedge overall economy-wide mortality risk, have been proposed, but these bonds have challenges and the proponents have not shown how governments are hedged. This paper recommends that...

Investment managers require a consistent asset pricing model, asset allocation recommendations and risk-adjusted performance measures (or the “three facets of investing”) to be effective in managing portfolios. Incorporating three critical realities of investing into these models (i.e., that...

This paper makes a simple but bold argument that because mean-variance optimization (MVO) and the capital asset pricing model (CAPM) were derived from a theoretical construct rather than reality, they represent a specialized case of a more general theory. We suggest a theory based on the...

Prof, Andre Perold has shown how the Capital Asset Pricing Model (with implications for asset pricing and risk-adjusted performance) can be derived from maximizing the Sharpe ratio as opposed to the traditional approach of assuming that investors maximize the utility of wealth. More recently,...

Using case studies of two investment companies, this paper highlights that organizations may have “investment tribes,” i.e., groups of individuals who appear to exhibit similar risk tendencies for gambles involving gains or losses, possibly with a wide spread of risk preferences. Tribes and...
