This paper proposes a new centrality measure called overall centrality measure that can be used to summarize the important information contained in social network. It is an optimal linear combination of the traditional measures where the optimality criterion is similar to that in principal component analysis. The advantages of this method will be illustrated by using stocks prices in Indonesian Stock Exchange where the relationship among stocks is viewed as social relationship. Some important results will be highlighted.
