The first priority will be to rein in all militias from both sides and ensure security returns to the country.
Extremely fragmentary data suggest that security returns were also less than spectacular in that earlier eraAnother way of looking at the issue is that primtive societies have very high interest rates because of the risks involved.
The aim of this paper is to solve the portfolio selection problem when security returns contain both randomness and fuzziness.
This paper proposes two new models for portfolio selection in which the security returns are stochastic variables with fuzzy information.
I have always been impressed by the inexorable tendency for reversion to the mean in security returns.
But until security returns to the war-torn country, few investors are willing to take the risk.
In the eyes of the committee, a more substantial investment in global health will yield diplomatic, economic, and security returns.
Two numerical examples with security returns taking different types of membership function are also given to illustrate the modelling idea of the paper and to demonstrate the effectiveness of the proposed algorithm.
Since the observed values of security returns in real-world problems are sometimes imprecise or vague, an increasing effort in research is devoted to study the properties of risk measures in fuzzy portfolio optimization problems.
This paper responds to Perkins' (2016) preferred methodology association study rather than the use of an event study research design in Olibes' (2016) paper (Security Returns and Volume Responses around International Financial Reporting Standards (IFRS) Earnings Announcements).
"While we find a presidential cycle exists in security returns, our evidence also implies that investors could have most effectively capitalized on the pattern by examining the actions of policymakers".
