This comprehensive corporate financial management report is divided into two parts. Part A focuses on stock market indices, specifically the Australian Securities Index (ASX), logarithmic returns, portfolio analysis, and beta calculations. It examines the weak form market efficiency hypothesis using t-tests and presents the findings. Part B delves into the weighted average cost of capital (WACC), the Gordon's Growth Model, and the Capital Asset Pricing Model (CAPM). It also analyzes the debt-to-equity ratio (D/E) and the correlation between WACC and D/E, using the Goodman Group as a case study. The report offers theoretical analysis and concludes with references, providing a detailed overview of financial concepts and their application in the corporate world.
