Subdiffusive processes can be used in finance to explicitly accommodate the presence of random waiting times between trades or "duration", which in turn allows the modelling of price staleness effects. Option pricing models based on subdiffusions are incomplete, as they naturally account for the...

In this paper we present an application where advanced undergraduate students can solve the expected utility portfolio model with a risk-free and a risky asset with both up and down returns in the Stock Market. With real Stock Market data, we use Excel Solver to find the portfolio decision and...

Handling risk factors in the context of a multi-asset risk parity portfolio allocation has created increased interest in recent literature. When allocating along risk factors through principal components, one major problem that persists is the potential existence of leverage or short positions...

Exact analytical solutions to the problem of computing a minimum semivariance portfolio cannot be obtained due to the endogeneity of the semicovariance matrix. However, when the number of assets is small, the weights for such a portfolio can be determined numerically. This paper presents the R...

We posit a fund manager and an individual investor who maximize the expected (log) utility of their respective terminal wealth. The manager possesses more information than the investor does and charges the latter, her would-be customer, a linear compensation fee. The investor will delegate his...

In the existing financial literature, entropy based ideas have been proposed in portfolio optimization and in model calibration for options pricing. The abstracted problem corresponds to finding a probability measure that minimizes Kullbach-Leibler (KL) distance with respect to a known measure...
