Narrow Results

This paper represents a contribution to the empirical literature on systematic risk at a sectoral level in an emerging market, the Mexican Stock Market, incorporating all the available information of the different asset quoted prices for the beta calculation. We estimate the fuzzy beta coefficients for individual stocks as well as for sectoral indices comparing the results with OLS beta coefficients. Then, we contrast if the fuzzy estimations verify two hypothesis of the traditional portfolio theory, specifically those related to the influence of the number of stocks and the length of estimation period over beta stability. The methodology used to calculate the fuzzy beta coefficients is the fuzzy linear regression. The results suggest that, in the Mexican Stock Market, hypotheses of the portfolio theory are also verified when the return of the portfolio is considered as an uncertain data.

The main purposes of this paper are (i) to review investment, financing, dividend, and production policies in some detail; (ii) to discuss how these four policies are interrelated and integrate these four policies into a composite policy; (iii) to discuss the impacts of financing, dividend, and production policies on the beta coefficient; and (iv) to develop hypotheses to be used for empirical studies on the interaction among financing, dividend, and production policies. A theoretical relationship between beta coefficient and financing, dividend, and production policies is developed. This paper gives an overall view of the four policies used in finance education and research for the last five decades.

The primary purpose of this paper is to discuss how to use the active and interdisciplinary approaches to teach corporate finance. First, I describe the content and structure of the book entitled Corporate Finance and Strategy: An Active Learning Approach [Lee, CF, AC Lee, JC Lee and M Lee (2022). World Scientific]. Second, I discuss how the interdisciplinary approach is used to integrate corporate finance and strategy with other subjects. Third, I discussed how I require students to write three projects to make this course become active instead of passive to learn corporate finance. Finally, I discuss how students can benefit from active and interdisciplinary approach to learn finance.

This chapter offers some simplifying assumptions that reduce the overall number of calculations of Markowitz models through the use of the Sharpe single-index and multiple-index models. Besides single-index model, we also discuss how multiple-index model can be applied to portfolio selection. We have theoretically demonstrated how single-index and multiple-index portfolio selection models can be used to replace Markowitz portfolio selection model. An Excel example of how to apply the single-index model approach is also demonstrated.

The main purposes of this chapter are (i) to discuss risk classification and estimation; (ii) to show how to use minimum-variance and Sharpe performance measure approach to estimate optimal weights for a two-security portfolio; (iii) to discuss applications of performance measures; and (iv) to use concepts discussed in this chapter to show how banking lending rate can be estimated.
