Understanding Investment Concepts: Expected Returns, Minimum Variance Portfolios, and Utility
1. Below is given the log returns of asset X for 4 years. The standard deviation of the log returns is 5.39 %. Calculate the expected return of the asset (this means the arithmetic mean of the asset)- 1.15% 0.91% -0.04% 3.65% 1.77% 1.80% 3.36% -1.96% -0.12% -0.12% 3.50% 0.09% Step1- Calculate the average in this case = 0.0115,0.0091,(0.0004),0.0365,0.0177,0.0180,0.0336,(0.0196),(0.0012),(0.0012) ,0.0350,0.0009 add all and divide by 12 which = 0.0117 then + ½ (( 0.0539 )^2) = 0.0131 then convert

Objective 1: Solve a Linear Equation
Concepts and Rules:
- A linear equation is in the form of ax + b = c, where a, b, and c are real numbers.
- The goal is to isolate the variable (x) on one side of the equation.
- Balancing: Perform the same operation on both sides to maintain equality.
Step-by-Step Solving Process:
- Start with the equation in the form ax + b = c.
- Use inverse operations to isolate x:
- To remove/add a constant (b): Perform the opposite operation
Multiple Regression Analysis in Estimating Annual Salary
Multiple Regression Analysis
Multiple regression analysis is an extension of simple regression analysis. It uses two or more independent variables to estimate the value of a dependent variable. This method identifies the best-fitting line based on the method of least squares.
Additional Concepts
- Constant (b0 intercept): The value of the dependent variable (DV) in the regression equation when all independent variables (IVs) are equal to 0.
- Partial Regression Coefficient (conditional coefficient): Shows
