This report provides a comprehensive statistical analysis of stock returns for General Dynamics (GD) and Boeing (BA), along with the S&P 500 (GSPC). The analysis includes calculating returns, conducting Jarque-Berra tests to assess normality, evaluating the risk-return relationship, and performing hypothesis tests to compare average returns and variances. The Capital Asset Pricing Model (CAPM) is employed to estimate beta and interpret its significance, along with R-squared and confidence intervals. The report also examines whether GD stock is a neutral stock and assesses the normality of error terms in ordinary least squares regression. Statistical software like Microsoft Excel and SPSS were used for computations and analysis, with detailed results presented in tables and interpretations provided for each test and model.
