Intermarket analysis is a branch of technical analysis that examines the correlations between four major asset classes: stocks, bonds, commodities, and currencies. In his classic book Trading with Intermarket Analysis, John Murphy notes that chartists can use these relationships to identify the stage of the business cycle and improve their forecasting abilities. There are clear relationships between stocks and bonds, bonds and commodities, and commodities and the Dollar. Knowing these relationships can help chartists determine the stage of the investing cycle, select the best sectors and avoid the worst performing sectors Conclusions Intermarket analysis is a valuable tool for long-term or medium-term analysis. While these intermarket relationships generally work over longer periods of time, they are subject to draw-downs or periods when the relationships do not work. Big events, such as the 2008 US Financial crisis, can throw certain relationships out of whack for a few months. Furthermore, the techniques shown in this article should be used in conjunction with other technical analysis techniques. The Industrial Metals/Bond Ratio chart could be part of a basket of broad market indicators designed to assess the overall strength or weakness of the stock market. One indicator or one relationship should not be used on its own to make a sweeping assessment of market conditions.
