11:40 am PST. The High yield corporate bond etf, HYG is at risk of breaking down from the up-trendline. If it does, that spells bearishness for the U.S. core indices too as the HYG tracks the Dow. If HYG breaks down, then it could drop to $80, possibly $77.50. There was a 1,795,376 share block trade at 86.44 and we are below that now, but bouncing off the trendline.
