Chartists can use the Correlation Coefficient to understand the relationship between Treasury yields and certain groups, such as banks, utilities and REITs. The chart below shows the 10-year Treasury Yield ($UST10Y) in the main window and seven correlations in the indicator windows. I am using weekly data, a 13-week Correlation Coefficient and a 26-week EMA for further smoothing. This extra smoothing is because I am simply trying to determine the general tendency. This is clearly not a trading vehicle, but rather an observation to be considered along with the price chart for each ETF.
