The interaction between portfolio holdings contributes to the overall portfolio risk.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Correlation<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">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\n\n\n<p class=\"wp-block-paragraph\">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\n\n\n<div style=\"margin: 18px 0;\"><a style=\"display: block; text-align: center; padding: 14px 18px; border: 2px solid #2F5BFF; border-radius: 18px; color: #ffffff ; font-weight: 600; font-size: 16px; text-decoration: none; background-color: #1a73e8 ;\" href=\"https:\/\/analystprep.com\/free-trial\/\" target=\"_blank\" rel=\"noopener noreferrer\">Master uncorrelated portfolio holdings with AnalystPrep\u2019s Free Trial. <\/a><\/div>\n\n\n\n<p class=\"wp-block-paragraph\">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\n\n\n<p class=\"wp-block-paragraph\">Correlation plays a crucial role in risk diversification. Assets with negative correlations, like Beachwear and DVD rental, move in opposite directions, providing a hedge against risk. Lower correlations generally mean lower risk, but finding assets with significantly low correlations can be challenging.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Historical returns may not always predict future returns accurately, but historical risk tends to remain relatively stable. Correlations among assets within the same country are consistent, while intercountry correlations have risen due to globalization.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Diversification across asset classes, countries, and industries is key to mitigating risk. Index funds offer a cost-effective way to diversify, especially for small portfolios. Investing in foreign countries and avoiding over-investment in one&#8217;s employer&#8217;s stock are also recommended diversification strategies.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Insurance and investments with negative correlations, like gold, can further reduce portfolio risk. Options such as put options provide protection against significant losses, albeit with associated costs. Overall, diversification is vital for a resilient portfolio that can weather market fluctuations.<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<h2 class=\"wp-block-heading\"><strong>Question<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Given the following correlation coefficients, which two-asset portfolio combination is likely to exhibit the lowest risk?<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Asset A &#8211; Asset B correlation = 0.7.<\/li>\n\n\n\n<li>Asset A &#8211; Asset C correlation = 0.3.<\/li>\n\n\n\n<li>Asset B &#8211; Asset C correlation = 0.5.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">A.
