I guess I might as well enjoy when the PM curves are closely convergent - since it probably will not last too long!

That was a good read - it is consistent with what I found in my early explorations in financial time series analysis which provided a heuristic for later work. When a time series such as DJ price is examined as a "walk" with the result being a sum of -1,0,1 based on whether the price decreases, unchanged, or increased from the previous day - the number of + days was only slightly larger than the number of - days, but on average, the advances were of a larger magnitude.
