Negative correlation is a relationship between two variables in which one variable increases as the what does negative correlation mean decreases, and vice versa.
In statistics, a perfect negative correlation is represented by the value A perfect negative correlation means the relationship that exists between two variables is exactly opposite all of the time. Negative correlation or negaative correlation indicates that two individual variables have a statistical relationship such that their correlatlon generally move in opposite directions from one another. If, for instance, variables X and Y have a negative correlation clrrelation are negatively correlatedas X increases in value, Y will decrease; similarly, if X decreases in value, Y will increase.
The degree to which one variable moves in relation to the other is measured by the correlation coefficientwhich quantifies the strength of the correlation between two variables. For example, if variables X and Y have a correlation coefficient of The negaitve the negative correlation between two variables, the closer the correlation coefficient will be to the value The correlation coefficient, usually denoted by "r" or "R", can be determined by regression analysis. The square of the correlation coefficient generally denoted by "R 2 ", or R-squared represents the degree or extent to which the variance of one variable is related to the variance of the second variable, xoes is typically expressed in percentage terms.
For example, if a portfolio and its benchmark have a correlation of 0. The degree of correlation between two variables is not static, but can swing over a wide range—or from positive to negative, and vice versa—over time.
The concept of negative correlation is a key one in portfolio construction. Negative correlation between sectors or geographies enables the creation what does negative correlation mean diversified portfolios that can better withstand market volatility and smooth out portfolio returns over the long term. Consider the long-term negative correlation between stocks and bonds.
Stocks generally outperform bonds what does negative correlation mean periods of strong economic performance, but as the economy slows down and the central bank reduces interest rates to stimulate the economy, bonds may outperform stocks. Thus, the overall return on your portfolio would be 6. Equities and bonds generally have a negative voes, but in the 10 years totheir correlation has ranged from approximately Examples of negative correlation are common in the investment world.
A well-known example is the negative correlation between crude oil prices and airline stock prices. Jet fuel, which is derived from crude oil, is a large cost input for airlines and has a significant impact on their profitability and earnings. If the price of crude oil what is ss ds memory up, it could have a negative impact on airlines' earnings and hence on the price of their stocks.
But if the price of crude oil trends lower, this should boost airline profits and therefore their stock prices. Here's how the existence of this phenomenon can help in the construction of a diversified portfolio.
As the energy sector has a substantial weight in most equity indicesmany investors have significant exposure to crude oil prices, which hwat typically quite volatile. As the energy sector, for obvious reasons, has a positive correlation with crude oil prices, investing part of one's portfolio in airline what does negative correlation mean would provide a hedge against a decline in oil prices. It should be noted that this investment thesis may not work all of the time, as the typical negative correlation between oil prices and airline stocks might occasionally turn positive.
For example, during an economic boom, oil prices and airline stocks may both rise; conversely, during a recessionoil prices and airline stocks could slide in tandem. Correlatlon negative correlation between two variables breaks down, it can play havoc with investment portfolios. For example, US equity markets experienced their worst performance in a decade in the fourth quarter ofpartly fueled by concerns that what does negative correlation mean Federal Reserve Fed would continue to raise interest rates.
Fears of rising rates also took their toll on bonds, leading their normally negative correlation with stocks to fall to the weakest what does negative correlation mean in decades. At such times, investors often discover to their chagrin that there is no place to hide. Fundamental Analysis. Financial Analysis. Portfolio Construction. Technical Analysis. Your Privacy Rights.

Types of correlation coefficients
Apr 02, · A negative correlation between two variables means that one decreases in value while the other increases in value or vice versa. A negative correlation is written as “” In other words, while x gains value, y decreases in value. Feb 08, · In layman terms, Negative Correlation is a relationship between two variables. They are part of a function in which dependent and independent variables move in different directions in terms of value. For example, if the independent variable increases, the . Jul 14, · A negative correlation is a relationship between two variables such that as the value of one variable increases, the other decreases. Correlation is expressed on a range from +1 to -1, known as the correlation coefficent. Values below zero express negative nowlovestory.com: Ivy Wigmore.
Correlation is a statistical term that describes the relationship between two variables or datasets. The type of correlation two variables have is entirely dependent upon the variables themselves. Understanding how correlation works is particularly useful for business owners and portfolio managers. To better understand correlation, it is important to know the various types and whether the relationships are positive, zero or negative.
In this article, we will focus on negative correlation, the definition, its importance and how to calculate it. A negative correlation between two variables means that one decreases in value while the other increases in value or vice versa.
Consider the following variable examples that would produce negative correlations. It is also important to note that in some circumstances, correlations might change.
This is particularly true when it comes to stocks and bonds. Though these two variables tend to be negatively correlated, things could change as time passes. Here are some examples of negatively correlating variables:. The more you sleep, the less tired you'll feel. Negative correlation is just one statistical term used to identify data relationships between two variables. Here are the other ways that data variables can be described based on respective values:.
Positive correlations using similar example variables to those above would mean the following:. A correlation of zero means there is no relationship between the two variables. In other words, as one variable moves one way, the other moved in another unrelated direction. Statistically, a perfect negative correlation is represented by Zero correlations using similar example variables to those above would mean the following:. The correlation coefficient measures the strength of the relationship between two variables.
That said, if two datasets have a correlation coefficient of If they had a correlation coefficient of Using this knowledge, it can be said that the higher the negative correlation is, the closer the correlation coefficient will be to There are three types of correlation coefficients: Pearson correlation, Spearman correlation and Kendall correlation.
The type of correlation coefficient method you use is dependent upon the variables or datasets you're using. To understand the importance of a negative correlation, you need to understand Modern Portfolio Theory. This theory is a strategy concerned with the risk and return of a portfolio of assets. Under this theory, it is believed that you could minimize the potential for risk by having diversified financial assets.
By this belief, having a portfolio of all positive correlations, for example, could be volatile because the portfolio isn't diversified enough. While having a diverse portfolio can't eliminate all risks, it can still be beneficial when random events occur in the financial market. With that said, a negative correlation can help create diversified portfolios. This then reduces the risk of portfolio volatility and smooths out returns in the long run.
All in all, negative correlations can be helpful to managers determining how to allocate assets because portfolio managers can use them to help reduce a portfolio's volatility.
