SPY is breaching below a short-term daily downward trend at a significantly investor-interested zone.
The dark gold region represents a highly trafficked zone of interest during the greater part of the first of the year. After a rather short testing period around mid-May, the market drove higher before return to a short-term downtrend.
Now breaking below that trend (orange line), investors are faced with a choice to support the levels of earlier this year, or flee to safety.
