Abstract | This paper mainly proposes a new model for stock markets, namely a portfolio selection model with interval-valued return rates. To do it, we review some concepts of interval numbers and the acceptability function of rankings at first. And we present an improved ranking method for intervals. Then, we introduce set-valued random variables, the semi-variance and the semi-covariance of interval-valued random variables and prove some related properties. After the preparation, we introduce our new portfolio selection model of interval-valued return rates with semi-variances as risk measurements of stocks. Finally, we do an empirical analysis by using real stock data in NASDAQ stock market to illustrate our model. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
