Mean-risk models using two risk measures: A multi-objective approach [PDF]

open access: yes, 2006
This paper proposes a model for portfolio optimisation, in which distributions are characterised and compared on the basis of three statistics: the expected value, the variance and the CVaR at a specified confidence level.

Mean-standard deviation-conditional value-at-risk portfolio optimization [PDF]

open access: yesMathematics and Modeling in Finance, 2023
The use of variance as a risk measure is limited by its non-coherentnature. On the other hand, standard deviation has been demonstrated as acoherent and effective measure of market volatility. This paper suggests theuse of standard deviation in portfolio
