The calculation of portfolio variance considers not only the riskiness of individualassetsbut also the correlation between each pair of assets in the portfolio. Thus, the statistical variance analyzes how assets within a portfolio tend to move together. The general rule of portfoliodiversificationis th...
From this formula, it is clear that calculation of an incremental VaR, i.e. the effect of a new position to the existing portfolio VaR requires us to compute the VaR of the updated portfolio as well as the VaR of an existing portfolio. However, there is a shortcut. In particular, we...

Today, we delve into a critical concept that can make or break investment decisions: portfolio variance. Whether you’re a seasoned investor or just starting out ...
As the number of assets in the portfolio grows, the terms in the formula for variance increase exponentially. For example, a three-asset portfolio has six terms in the variance calculation, while a five-asset portfolio has 15.Using software like Excelcan make the calculation of these numbers e...

Portfolio beta is an important input in calculation of Treynor's measure of a portfolio.FormulaPortfolio beta equals the sum of products of individual investment weights and beta coefficient of those investments. It is a measure of the systematic risk of the portfolio. ...
And it is a measure of the riskiness of a portfolio. Examples of Portfolio Return Formula (With Excel Template) Let’s take an example to understand the calculation of Portfolio Return in a better manner. You can download this Portfolio Return Formula Excel Template here –Portfolio Return Form...
The alpha calculation formula can be used first by calculating the expected rate of return of the portfolio based on the risk-free rate of return, a beta of the portfolio, and market risk premium, then deducting the result from the actual rate of return of the portfolio. Alpha of portfolio...
Critical discussion made on "why calculating the expected portfolio return is easy but the harder part is to work out with the calculation of the risk component of the portfolio"? Two important portfolio risk measuring parameters, namely variance and covariance are introduced in detail. Thereafter,...
Roy's safety-first ratio is similar to the Sharpe but introduces one subtle modification. Rather than comparing portfolio returns to the risk-free rate, the portfolio's performance is compared to a target return. This is the formula:
