چکیده
I nvestors with cash that is destined for stocks often use a dollar-cost averaging plan. They divide the cash into segments, and convert one segment at a time from cash to stocks according to a predetermined schedule. The alternative to dollar-cost averaging is lump-sum investment. The popularity of dollar-cost averaging can be traced back at least to the 1940s. (See, for example, discussions in Ketchum [1947], Solomon [1948], and Weston [1949].) And that popularity has never waned. For example, Clements [1994] writes in a Wall Street Journal column "aimed at ordinary investors who want to get their finances going in the right direction":

ADAPTIVE ORDERED WEIGHTED AVERAGING FOR ANOMALY DETECTION IN CLUSTER-BASED MOBILE AD HOC NETWORKS
In this paper, an anomaly detection method in cluster-based mobile ad hoc networks with ad hoc on demand distance vector (AODV) routing protocol is proposed. In the method, the required features for describing the normal behavior of AODV are defined via step by step analysis of AODV and independent of any attack. In order to learn the normal behavior of AODV, a fuzzy averaging method is used fo...
متن کاملMinimizing the supplying cost of leverage items: a mathematical approach
In the new competitive environment, selecting and planning of the supply chain is very crucial and involves evaluation of many factors. Different approaches have been applied to assess the supplier/s. Most of these studies are based upon the supplier/s' capabilities. It may be neither rational nor economical to deal with each item via a generic material control system. Furthermore, supplier...
متن کاملRational Choice Theory: An Overview
It seems easy to accept that rationality involves many features that cannot be summarized in terms of some straightforward formula, such as binary consistency. However, this recognition does not immediately lead to alternative characterizations that might be regarded as satisfactory, even though the inadequacies of the traditional assumptions of rational behavior standard used in economic theo...
متن کاملA Statistical Comparison of Value Averaging vs. Dollar Cost Averaging and Random Investment Techniques
As the title suggests, this paper compares two “formula” or mechanical investment techniques, dollar cost averaging and a relatively new proposal, value averaging, to a form of random investing to determine if any technique yields superior investment performance. Results indicate that value averaging does provide superior expected investment returns when investment prices are quite volatile and...
