When you calculate a portfolio's beta, you are essentially measuring its sensitivity to these market-wide movements. For example, if the market rises 10%, a portfolio with a beta of 1.
Portfolio Beta Calculation Example: Step-by-Step Weighted Average
A beta of 1. 0 would historically rise approximately 10%, and vice versa for declines.
Step-by-Step Weighted Average The calculation follows a logical sequence: identify the beta and market value of each holding, calculate the weight of each holding by dividing its value by the total portfolio value, and then multiply each holding's weight by its beta. Historical beta relies on past price data, using statistical regression to analyze how the portfolio reacted to market changes over a specific period.
Portfolio Beta Calculation Example: Step-by-Step Weighted Average
Fundamental beta, on the other hand, attempts to predict future volatility by analyzing the composition and characteristics of the portfolio's holdings, such as the individual betas of constituent stocks. Once you have these individual betas, you cannot simply average them; you must weight them according to the percentage of the total portfolio value that each asset represents.
