The 3D Contour of The Bubble Index Contour: TNX (1962 – 2015) displays an important prediction. As you can see from the graphs and contours, it appears to have peaked in the window range 7,200 – 8,200. This would indicate that the bubble in the US Gov’t 10 – Year Bond recently ended. That is cautioned by an unknown factor — that there is not a bubble forming on a much larger time window than I was able to calculate (13,200 days +).
