Why correlation is important with respect to portfolio returns?

What is the ideal correlation for a portfolio?

A correlation of 1.00 indicates perfect correlation, while lower numbers indicate that the asset classes are not correlated and generally do not move in tandem with each other—or, when the market moves down, these asset classes may not fall as much as the market in general, which could mitigate risk in your portfolio.

Why are covariances or correlations important in selecting a portfolio?

Covariance is used in portfolio theory to determine what assets to include in the portfolio. … Modern portfolio theory uses this statistical measurement to reduce the overall risk for a portfolio. A positive covariance means that assets generally move in the same direction.

Should you keep stocks in your portfolio which have positive correlation?

Positively correlated stocks tend to move up and down together, while negatively correlated stocks tend to move in opposite directions. Combining negatively correlated stocks in a portfolio can help investors reduce risk; such portfolios, however, also limit the investor’s profit potential.

How does the correlation between the stocks in a portfolio affect the portfolio’s volatility? The lower the correlation between stocks, the lower the portfolio’s volatility.

How do you find the correlation of a portfolio?

To find the correlation between two stocks, you’ll start by finding the average price for each one.

Next, you’ll calculate a daily deviation for each stock.
