CFV, 958.67. CM, 1038.64. FV, 1118.62. OM, 1169.62. OFV, 1220.62.
I am also going to keep track of the difference of the two mids, called d2M.
d2M, 1104.13.
Note that if you are optimistic, you should be mildly long here, since OFV is 13 above SPX. Another interesting signal is if d2M crosses above or below FV. As we can see, 2dM is currently below FV. We might use d2M to decide whether to be pessimistic or optimistic depending on whether it is above or below FV, although it might be too volatile.
In essence what I have done with d2M is build my own version of MACD for FV, although it has nothing to do with that equation or mathematics. It is simply the same in spirit.
