I want to construct my own index: 3-Year Moving Average based on the 5-Year CMT that changes Monthly. How do I go about doing that?
Just add the 36 most recent monthly values for the 5-Year CMT together and divide the result by 36. Historical Data: Mortgage-X compiles historical values for the indexes which are widely used on adjustable rate mortgages (ARMs).
