Summary Introduction

To select: Thereal estate return of which property affects the portfolio risk is to be determined.

Introduction : The portfolio risk is defined as the combination of assets which carries its own risk with each investment.

The standard deviation is used to determine that in which manner the values from a data set vary from its mean value. This is calculated by the square root of the variance.

standard deviation=variance

The expected return is defined as the return which is obtained on the risky asset that is expected in future.

Correlation represents the relation between the two data sets. It shows that in which manner it corresponds to the changes in the value of alternate set. When the one data is increased and along with other is also increasing or vice-versa, then it is called as positive Correlation.

ExponentialSmoothing Week α = 0.1 α = 0.2 13 (b) Applying the MSE measure of forecast accuracy, would you prefer a smoothing constant of α = 0.1 or α = 0.2 for the gasoline sales time series? An smoothing constant provides a more accurate forecast, with an overall MSE of . (c) Are the results the same if you apply MAE as the measure of accuracy? An smoothing constant provides a more accurate forecast, with an overall MAE of . (d) What are the results if MAPE is used? An smoothing constant provides a more accurate forecast, with an overall MAPE of .

After many sunset viewings at SUNY Brockport, Amanda dreams of owning a waterfront home on Lake Ontario. She finds her perfect house listed at $425,000.

Imagine that the SUNY Brockport Student Government Association (SGA) is considering investing in sustainable campus improvements. These improvements include installing solar panels, updating campus lighting to energy-efficient LEDs, and implementing a rainwater collection system for irrigation. The total initial investment required for these projects is $100,000. The projects are expected to generate savings (effectively, the cash inflows in this scenario) of $30,000 in the first year, $40,000 in the second year, $50,000 in the third year, and $60,000 in the fourth year due to reduced energy and maintenance costs. SUNY Brockport’s discount rate is 8%. What is the NPV of the sustainable campus improvements? (rounded) a- $70,213b- $48,729c- $45,865d- $62,040
