I've written before that fourth waves are my arch-nemesis. As a trader, I largely avoid trading them unless I have a clear read. As an analyst, I don't have the luxury of ignoring a market -- all I can do is what I've been doing for the past few weeks: warn that the wave structure was unclear to me, and that, while I was leaning very slightly bearish, it was entirely possible that wave iv had bottomed at 1560.
