Yesterday’s exhilarating plunge may have felt special, but on the hourly chart (see inset) it was of a piece with the chop-and-slop price action of the last few weeks. Is it the initial rumbling of an avalanche? We may be better able to answer that question after we’ve seen how aggressively sellers attack a Hidden Pivot support at 1286.50. That’s my minimum downside projection at the moment, but look out below next week if it’s decisively exceeded, especially on a closing basis.
