关键词： Investor   Globalization   Perception   Investment   SPERTEL  

摘要： The globalization of financial markets has been increasing the retail investors’ community over the past two decades by providing a wide variety of market and investment options. However, it makes much more complex in their investment decisions process. The market conditions can be influenced by both fundamental factors of the company and external factors such as social, political, economic, regulatory, technological, environmental and legal (SPERTEL) that have an influence on the values of equity shares. The main objective of the study is to analyze the investors’ perception in the influence of Social, Political, Economical, Regulatory, Technological, Environmental and Legal (SPERTEL) risks on the value of equity shares in the market. Based on the perception of the investors taken for this study in Tamil Nadu, SPERTEL risk has influence over the market price of the equity share. It is to be noted that except for the social factors between married and unmarried investors, political, regulatory and legal factors for age and occupation, all other factors seemed to be insignificant.

关键词： 股票价值投资   理论   应用  

摘要： 股票价值投资是基于股票价值本身的长期性投资,它是在对企业业绩、行业景气度和经济的基本面进行综合考量后所作出的投资结论。价值投资实施的前提应该是经济发展比较平稳,企业业绩持续增长,同时相关股票的价格在启动价值投资策略时并不是非常高,处于比较合理的状态中,如果同时满足这几个情况,那么价值投资是有效的。

摘要： The use of biofuels, such as bioethanol or biodiesel, has rapidly increased in the last few years. Near infrared (near-IR, NIR, or NIRS) spectroscopy (>4000 cm(-1)) has previously been reported as a cheap and fast alternative for biodiesel quality control when compared with infrared, Raman, or nuclear magnetic resonance (NMR) methods;in addition, NIR can easily be done in real time (on-line). In this proof-of-principle paper, we attempt to find a correlation between the near infrared spectrum of a biodiesel sample and its base stock. This correlation is used to classify fuel samples into 10 groups according to their origin (vegetable oil): sunflower, coconut, palm, soy/soya, cottonseed, castor, Jatropha, etc. Principal component analysis (PCA) is used for outlier detection and dimensionality reduction of the NIR spectral data. Four different multivariate data analysis techniques are used to solve the classification problem, including regularized discriminant analysis (RDA), partial least squares method/projection on latent structures (PLS-DA), K-nearest neighbors (KNN) technique, and support vector machines (SVMs). Classifying biodiesel by feedstock (base stock) type can be successfully solved with modern machine learning techniques and NIR spectroscopy data. KNN and SVM methods were found to be highly effective for biodiesel classification by feedstock oil type. A classification error (E) of less than 5% can be reached using an SVM-based approach. If computational time is an important consideration, the KNN technique (E=6.2%) can be recommended for practical (industrial) implementation. Comparison with gasoline and motor oil data shows the relative simplicity of this methodology for biodiesel classification. (C) 2011 Elsevier B.V. All rights reserved.
