That sounds like a horror movie title. Back when this blog was free, I regularly featured a group of breadth indicators that proves usefull when markets were full of non-trending swings. That usefulness declined, somewhat, during the strong trending collapse of 2008. But something else happened as well – the reliability of the yahoo advance decline statistics deteriorated markedly. Now all advance decline statistics these days are suspect, as there are so many sources who calculate them differently given the various off-exchange trading that goes on. But any data set may be useful as long as its consistent. What doesn’t work is to splice an old data set on to a new one – that’s what climate ‘scientists’ do to prove their pre-ordained conceptions (but I digress).  So, some months ago I began recollecting a new source of breadth data (Bloomberg) and am bringing back some of those indicators (and a new one) to assist us in getting a reliable read on the doings on Wall Street.
