There's a lot to be about long term, but immediately there's pricing action, accumulation, and .
Pricing shows that the dip double bottomed, and while it's true a conservative investor would wait for it to clear the ~$435 range, I would purchase and would be careful around that range, watching for any signs of weakness.
The is approaching a cross with a pretty big upswing. Keep an eye out for rejection at the cross, that might send it back for a triple bottom.
Accumulation is returning, always a sign that the worst is over. As accumulation returns the pricing action will definitely follow. If you're looking for a more conservative play, wait until the accumulation clears the peak on August 1.
