it seems like there is some correlation just recently (since the last and final rate cut) between TNX and SPX, but I am having trouble charting it. some people are suggesting when oil sells, the indices respond positively, but I am having trouble finding that correlation as well. what's the best way to test a correlary? loaded question, I know. but if there is a leading indicator, what is it? This link I don't care for, but illustrates my issue maybe <img src=http://ichart.finance.yahoo.com/z?s=%5ETNX&t=5d&q=l&l=on&z=m&c=%5EGSPC&a=v&p=s> <a href="http://finance.yahoo.com/q/bc?t=5d&s=%5ETNX&l=on&z=m&q=l&c=&c=%5EGSPC" target="_blank">http://finance.yahoo.com/q/bc?t=5d&s=%5ETNX&l=on&z=m&q=l&c=&c=%5EGSPC</a>
