Cup and HandleCostco formed a head a shoulders pattern a while back and experienced a deep pull back.
Looks to be recovering from the rising wedge pattern with very little disruption.
Cup and handle patterns are calculated using cup depth.
No recommendation.
If you like a stock, sometimes you can do well by waiting for the fall to complete from an ugly top or a head a shoulders pattern, then buying at the bottom. Some prefer getting in closer to the top. We are all different.
