The chart below shows how the correlation between U.S. Treasury yields and the Dow Jones Industrial Average has varied under each iteration of the quantitative easing program of bond purchases the Federal Reserve has employed since the financial crisis. Under QE3 (the current iteration), changes in bond yields have have been associated with larger changes in equity prices than under any other program. So, when yields rise, so do equities, and when yields fall, so do equities — in both directions moreso than in the past. The red square near the top of the chart plots the current levels of the yield on the 10-year Treasury note and the DJIA. Its place above the regression line shows that equities are looking rich based on this relationship.
