A new approach to mean-variance efficient portfolio selection is introduced. The method is based on realized regression theory and the regression based portfolio selection approach of Britten-Jones (1999), yielding a conditional version of the Britten-Jones (1999) method. Some of the noticeable results of the paper are as follows. Firstly, the monetary union may have had a much less important i...

in this study, trading patterns and constituents of trading performances of individual and institutional investors have been investigated in a weekly manner, using an auto regressive model and a grinblatt & titman portfolio performance measure spanning 2008-2012. the results show that while individual investors have a herding behavior, institutional investors take contrarian trading strategies....

The purpose of this study is to help bio-tech firms solve the foreign investment (FI) entry mode selection problem. This study combines the concepts of factor analysis, analytic hierarchy process (AHP), genetic algorithm (GA), and fuzzy integral to construct an entry mode selection approach. This study produces several interesting findings. (1) In the different investment entry modes, there are...

Selection effects include seemingly independent influences on, and choices in, conducting and reporting primary research that may bias a stock of knowledge. Such effects may arise from sociopolitical influences (research priority selection), researcher choices (methodology selection), peer review influences (publication selection), and metaanalyst choices (metadata sample selection). This paper...

the stock selection problem is one of the major issues in the investment industry, which is mainlysolved by analyzing financial ratios. however, considering the complexity and imprecise patterns ofthe stock market, obvious and easy-to-understand investment rules, based on fundamental analysis,are difficult to obtain. fundamental and technical analyses are two common methods for predictingthe fu...

Are countries with unregulated capital flows more vulnerable to currency crises? Efforts to answer this question properly must control for self-selection bias, because countries with liberalized capital accounts may also have sounder economic policies and institutions that make them less likely to experience crises. We employ a matching and propensityscore methodology to address this issue in a...

The prediction of a stock market direction may serve as an early recommendation system for short-term investors and as an early financial distress warning system for long-term shareholders. In this paper, we propose an empirical study on the Korean and Hong Kong stock market with an integrated machine learning framework that employs Principal Component Analysis (PCA) and Support Vector Machine ...

ANY mutant stocks of Drosophila mass cultured in the laboratory for generaM tions become phenotypically almost indistinguishable from wild type. Upon outcrossing, the mutant reappears in the FZ with its pristine strength of expression. Presumably, genes reducing the degree of expression, or expressivity, of the major character of the mutant stock had appeared and accumulated through natural sel...
