WebbModern portfolio theory (MPT), or mean-variance analysis, is a mathematical framework for assembling a portfolio of assets such that the expected return is maximized for a given level of risk. It is a formalization and extension of diversification in investing, the idea that owning different kinds of financial assets is less risky than owning only one type.

WebbStandard deviation tells us about the variability of values in a data set. It is a measure of dispersion, showing how spread out the data points are around the mean. ... Consider the following two data sets with N = 10 data points: A = {2, 4, 6, 8, 10, 12, 14, 16, 18, 20} Webb24 juni 2024 · P(x = 5) = 1 50. (5)( 1 50) = 5 50. (5 – 2.1) 2 ⋅ 0.02 = 0.1682. Add the values in the third column of the table to find the expected value of X: μ = Expected Value = 105 50 = 2.1. Use μ to complete the table. The fourth column of this table will provide the values you need to calculate the standard deviation.
