The interaction between portfolio holdings contributes to the overall portfolio risk.<\/p>\n<h2><strong>Correlation<\/strong><\/h2>\n<p>Correlation is a statistical measure of the relationship between two series. The series need not pertain to financial assets. In the context of a portfolio, the series will consist of the historical returns of two potential portfolio constituents.<\/p>\n<p>When the returns move in &#8220;lockstep&#8221; with one another, they are said to be perfectly correlated and have a correlation coefficient of +1. The converse implies a correlation coefficient of -1.<\/p>\n<p>When you put assets together in a portfolio with correlation coefficients less than +1 (they don&#8217;t have to be negatively correlated), it reduces the overall risk of the portfolio. Having uncorrelated assets means they don&#8217;t move together in the same direction all the time. This risk diversification leads to a portfolio with less volatility, and different assets contribute to the portfolio&#8217;s return at various times.<\/p>\n<blockquote>\n<h2><strong>Question<\/strong><\/h2>\n<p>Given the following correlation coefficients, which two-asset portfolio combination is likely to exhibit the lowest risk?<\/p>\n<ul>\n<li>Asset A &#8211; Asset B correlation = 0.7.<\/li>\n<li>Asset A &#8211; Asset C correlation = 0.3.<\/li>\n<li>Asset B &#8211; Asset C correlation = 0.5.<\/li>\n<\/ul>\n<p>A.
