Sigman 1 Portfolio mean and variance

Here we study the performance of a one-period investment X0 > 0 (dollars) shared among several different assets. Our criterion for measuring performance will be the mean and variance of its rate of return; the variance being viewed as measuring the risk involved. Among other things we will see that the variance of an investment can be reduced simply by diversifying, that is, by sharing the X0 a...

1 the Distribution of Loan Portfolio Value

The amount of capital necessary to support a portfolio of debt securities depends on the probability distribution of the portfolio loss. Consider a portfolio of loans, each of which is subject to default resulting in a loss to the lender. Suppose the portfolio is financed partly by equity capital and partly by borrowed funds. The credit quality of the lender's notes will depend on the probabili...

Modern Portfolio Theory, Digital Portfolio Theory and Intertemporal Portfolio Choice

The paper compares three portfolio optimization models. Modern portfolio theory (MPT) is a short-horizon volatility model. The relevant time horizon is the sampling interval. MPT is myopic and implies that investors are not concerned with long-term variance or mean-reversion. Intertemporal portfolio choice is a multiple period model that revises portfolios continuously in response to relevant s...

Cover’s Universal Portfolio, Stochastic Portfolio Theory and the Numéraire Portfolio

Cover’s celebrated theorem states that the long run yield of a properly chosen “universal” portfolio is as good as the long run yield of the best retrospectively chosen constant rebalanced portfolio. The “universality” pertains to the fact that this result is model-free, i.e., not dependent on an underlying stochastic process. We extend Cover’s theorem to the setting of stochastic portfolio the...

Portfolio Size in Stochastic Portfolio Networks Using Digital Portfolio Theory

The investment portfolio with stochastic returns can be represented as a maximum flow generalized network with stochastic multipliers. Modern portfolio theory (MPT) [1] provides a myopic short horizon solution to this network by adding a parametric variance constraint to the maximize flow objective function. MPT does not allow the number of securities in solution portfolios to be specified. Int...
