Two variables that move in opposite directions are said to be inversely related.
A negative correlation is a relationship between two variables that move in opposite directions. In other words, when variable A increases, variable B decreases. A negative correlation is also known as an inverse correlation.
The concept of negative correlation is important for investors or analysts who are considering adding new investments to their portfolio. When market uncertainty is high, a common consideration is re-balancing portfolios by replacing some securities that have a positive correlation with those that have a negative correlation.
Here are some common examples of a negatively correlated relationship between assets:
1. Oil prices and airline stocks
2. Gold prices and stock markets (most of the time, but not always)
3. Any type of insurance payoff
