How do you calculate the correlation of a portfolio?

How do you calculate the correlation of a portfolio?

The formula for correlation is equal to Covariance of return of asset 1 and Covariance of return of asset 2 / Standard. Deviation of asset 1 and a Standard Deviation of asset 2.

How do you calculate portfolio volatility?

Volatility for a portfolio may be calculated using the statistical formula for the variance of the sum of two or more random variables which is then square rooted. Alternatively, the volatility for a portfolio may be calculated based on the weighted average return series calculated for the portfolio.

How do you find the covariance of a portfolio?

The covariance of two assets is calculated by a formula. The first step of the formula determines the average daily return for each individual asset. Then, the difference between daily return minus the average daily return is calculated for each asset, and these numbers are multiplied by each other.

How do you measure portfolio diversification?

The correlation coefficient is calculated by taking the covariance of the two assets divided by the product of the standard deviation of both assets. Correlation is essentially a statistical measure of diversification.

How is risk measured in a portfolio?

Beta measures the volatility of a portfolio compared to a benchmark index. The statistical measure beta is used in the CAPM, which uses risk and return to price an asset. A beta greater than one indicates higher volatility, whereas a beta under one means the security will be more stable.

What is portfolio correlation?

When it comes to diversified portfolios, correlation represents the degree of relationship between the price movements of different assets included in the portfolio. A correlation of +1.0 means that prices move in tandem; a correlation of -1.0 means that prices move in opposite directions.

What is a good volatility percentage?

Defining market volatility comes with a surprisingly low bar: any time the market moves up and down by one percentage point or more over a sustained period, it’s technically considered a volatile market. That said, the implied volatility for the average stock is around 15%.

What is considered high volatility?

A stock with a price that fluctuates wildly—hits new highs and lows or moves erratically—is considered highly volatile. A stock that maintains a relatively stable price has low volatility. A highly volatile stock is inherently riskier, but that risk cuts both ways.

What risk is Diversifiable?

Specific risk, or diversifiable risk, is the risk of losing an investment due to company or industry-specific hazard. Unlike systematic risk, an investor can only mitigate against unsystematic risk through diversification.

What are the steps to calculate covariance?

1. Covariance measures the total variation of two random variables from their expected values.
2. Obtain the data.
3. Calculate the mean (average) prices for each asset.
4. For each security, find the difference between each value and mean price.
5. Multiply the results obtained in the previous step.

What is the ideal portfolio mix?

Your ideal asset allocation is the mix of investments, from most aggressive to safest, that will earn the total return over time that you need. The mix includes stocks, bonds, and cash or money market securities. The percentage of your portfolio you devote to each depends on your time frame and your tolerance for risk.

How is portfolio concentration measured?

Originally used in the context of quantifying diversification within an industry to assess the level of competition in the marketplace, the HHI can also be used to calculate portfolio concentration risk. The HHI is calculated by summing the squares of the portfolio share of each contributor.

Wie wird die Rendite des Portfolios berechnet?

Zuerst wird wieder die erwartete Rendite des Portfolios berechnet: werden, dass die Gewichte jeweils 1/3 betragen. Für die Formel bedeutet dies: Die erwartete Rendite des Portfolios beträgt also 15 %. Korrelationen zwischen den einzelnen Aktien beachten müssen. Die Formel für die Mit Leben gefüllt sieht sie dann wie folgt aus:

Wie benutzt man den Varianz-Rechner?

Der Varianz-Rechner kann verwendet werden, um die Varianz (Populationsvarianz und Stichprobenvarianz) einer Zahlenmenge zu berechnen. Die Stichprobenvarianz berechnet sich durch folgende Formel:

Wie sieht die Varianz in der Formel aus?

Wenn du die einzelnen Werte in die Formel einsetzt, sieht das so aus: Zuletzt willst du die Varianz berechnen. Als Zwischenschritt kannst du erst die Werte in den Klammern ausrechnen. Danach quadrierst du die Abweichungen und siehst den Faktor zusammen.
