Bonds are the dog that wag the equities tail. Bonds are way bigger than equities. Debt existed millennium before the first joint stock companies in Rome, and it was not until in the 1800's that limited liability stock companies were formed to attract capital. Credit is the basis of all capital formation and the rise and fall of nations. The interest rates control the bonds and bonds control stocks. Prac. Spec had bonds correlated well with equities. So it would make sense that the yield curve may give us information about the equities, in advance since it adds information to the bonds though term structure of interest rates. So study is to test the relationship of the yield curve to SP futures continuous to see if there is a correlation. Here's a start with data, yc is yield curve 10yr - 2 yr yield on CBOT index. YCC=percentage change, sp= es mini continuous spc=%ch. All closing.The reason is that I noticed that the yield curve seems to be ahead of sp by a day or so. Not sure exactly where to go with this but thought I'd give it a go with the hard core. I think the .12 correlation on n=274 is worth a look. Still starting to learn to script the lags +1 +5 etc on the series for test on predictiveness. Please work this over and give me a hand. I'm kind of over my head and its a long way to shore. > cor(cv$ycc,cv$spc) [1] 0.1228439 Date yc ycc sp spc 1 9/2/2003 3.649 NA 102200 NA 2 9/3/2003 3.647 -0.05480954 102700 0.48923679 3 9/4/2003
