Which eturn is higher?

Key Concepts

Expected Return

Expected return is a fundamental concept in finance that represents the anticipated average return on an investment, accounting for various possible outcomes weighted by their probabilities. It serves as a key metric for evaluating the potential performance of assets or portfolios and aids investors in making informed decisions.

Weighted Average Principle

The weighted average principle involves combining individual values by assigning each a factor that represents its relative importance in the overall set. In finance, this principle is applied when calculating portfolio returns, ensuring that each asset’s return contributes proportionately based on its share of the total investment.

Linearity of Expectation

Linearity of expectation is a statistical property stating that the expected value of a sum of random variables is equal to the sum of their individual expected values, regardless of any interactions between them. This concept underlies the equivalence between calculating a portfolio’s expected return by aggregating individual expected returns or by directly assessing the overall portfolio’s cash flows.
