Quote from Babak:
I thought that was pretty simple but ok, I'll explain. There are two charts superimposed on one another, the axis for the Dow (black) in to the right while the axis for the % of Dow stocks above their 50 day MA is to the left (green).
Notice that the 30% level is the beginning of an oversold level. In the past when it has reached that level (and surpassed it sometimes) stocks usually bounce back.
This is the only TA that I follow that would 'explain' the rally we are seeing. I noticed it a few days ago when it approached the 30% level but thought nothing of it since the other indicators I watch were not in agreement (of an oversold level).
Hope that's clear now.
