A bear would want to see it back off and resolve as a triangle into the FOMC at the end of the month. We can still find our way back to 2520 in a sensible way, preferably with a $VIX of 18 or lower.
The break from the triangle would be violent, potentially even more steep than what we are counting as the third wave. But it would mark a climax in the selling that would then reverse in a stronger and more sustained retrace.
At some point this year the real damage is done.
