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 Euro crisis or the US Financial crisis can throw certain relationships out of whack for a few months. Furthermore, the tools shown in this article should be used in conjunction with other technical analysis techniques. The XLY/XLP ratio chart and 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.
