Based on the distance (46) between the head and the neck, a long term price bottom of approximately 126 is appropriate, albeit only an approximation.
Regarding Goldmans recent movements, a key level for the past two months appears to be 150. While GS has for the moment bulled its way above that point, I would note that for the YTD is much higher when GS declines than when it rises. This is supportive of my theory that GS is still declining from a long term tops, as selling pressure is greater than buying pressure. This is also the case on its most recent movement to 154.65 - daily was at 6.489M compared to a moving average of 6.363M - not a strong enough spike to suggest the Bulls are back in charge of the big picture just yet, but completely in line with its previous bounces in the year to date.
Again, I'd love any critiques or comments at all.
Oh, as a side note I have no current or planned positions in GS - this chart is purely academic.
