Modern portfolio theory(MPT) addresses the problem of determining the optimum allocation of investment resources among a set of candidate assets. In the original mean-variance approach of Markowitz, volatility is taken as a proxy for risk, conflating uncertainty with risk. There have been many subsequent attempts to alleviate that weakness which, typically, combine utility and risk. We present ...

the aim of this study is to determine the formic features of modern sculpture. modern era has been an era filled with ups and downs for art world. in this article, modernism has considered the visual art movements, between 1890 and 1950 that with their innovations, have tried to be separating from the art of the past and have been confronting classical forms. although it is difficult to explain...

This paper provides an overview of how taxation affects household portfolio structure. It begins by outlining six aspects of portfolio behavior that may be influenced by the tax system. These are asset selection, asset allocation, borrowing, asset location in taxable and tax-deferred accounts, asset turnover, and whether to hold assets directly or through financial intermediaries. The analysis ...

I show that investment in housing plays a crucial role in explaining the patterns of cross sectional variation in the composition of wealth and the level of stockholdings observed in portfolio composition data. Due to investment in housing, younger and poorer investors have limited ̄nancial wealth to invest in stocks, which reduces the bene ̄ts of equity market participation. House price risk cr...

Methods to computing value-at-risk gradients with respect to portfolio positions have many applications. They include calculation of capital/reward efficient frontiers, hedging of derivative portfolios and optimal replication. We present a new algorithm for computing value-at-risk and its gradients. If the return can be decomposed as a sum of independent portfolio marginals, the pay-off distrib...

Background: Diagnostic ultrasound has been used to detect human disease especially fetus abnormalities in recent decades. Although the harmful effects of diagnostic ultrasound on human have not been established so far, several researchers showed it has had bioeffects in cell lines and in experimental animals. Three-dimensional (3D), four-dimensional (4D), and color Doppler sonography are new te...

In principle, implementation of portfolio investment strategies through market orders at the NYSE open would be problematic because of execution price uncertainty. This paper measures the impact, by comparing the actual value at the end of the trading day against the value one would have obtained if it were possible to observe opening prices when submitting orders. For positively weighted portf...

We consider a group of mean-variance investors with mimicking desire such that each investor is willing to penalize deviations of his portfolio composition from compositions of other group members. Penalizing norm constraints are already applied for statistical improvement of Markowitz portfolio procedure in order to cope with estimation risk. We relate these penalties to individuals’ wish of s...

Using the language of convex analysis we describe key results in several important areas of finance: portfolio theory, financial derivative trading and pricing and consumption based asset pricing theory. We hope to emphasize the importance of convex analysis in financial mathematics and also bring attention to researchers in convex analysis interesting issues in financial applications.
