Application Analysis of Portfolio Theory in Financial Markets

Based on portfolio theory, this paper reviews and summarizes the role of investors and examines two aspects of portfolio theory: the mean variance analysis method and the efficient limit model of the portfolio. And its limitations are analyzed. So that investors can invest better. Indifference curves vary from person to person, and deviations will likely affect the resulting final maximum utility point. Although the research on financial market risk has been relatively mature, there are still some puzzles to be solved in the effective measurement of risk. Markowitz takes the ROI as a representation of ROI and the variance as a representation of ROI, which solves the problem of measurement of asset risk. He thinks that most investors are risk-averse; they will try to avoid risk at the same time as they seek high returns. Therefore, Markowitz has proposed a portfolio investment theory based on the analysis of the mean variance.

Radiometric Mapping for The Identification of Hydrothermally Altered Zones Related to Gold Mineralization in Ife–Ilesa Schist Belt, Southwestern Nigeria

This study presents the interpretation of airborne gamma ray spectrometric data to delineate hydrothermally altered zones related to gold mineralization in the Ife–Ilesa Schist belt. K/eTh, Kd and F–Maps highlighting Potassic alterations related to gold mineralization were processed on the Oasis Montaj software and subsequently integrated using fuzzy logic modeling to produce the hydrothermal alteration map of the study area. The C–A fractal analysis was applied to the final hydrothermal map and was able to classify the study area into background, very low, low, moderate, high and very high alteration. These classes reflect the pervasive hydrothermal alteration style of the study area. The hydrothermally altered areas are evident on granitoids and areas proximal to it indicating that granitoids are proxies of heat source. Occurrence of active mining sites in the area agrees with the generated hydrothermal alteration map of the study area with 81% agreement. It therefore shows that radiometric method is a veritable method in mapping hydrothermal alteration areas. The use of radiometric method only cannot reliably map areas of gold mineralization as mineralization can be associated with several other processes. Hence, other methods involving geochemical and magnetic methods including GIS tools can be employed for further prospecting.
