COHR rebounded upward from a strong support level due to Rapid Accumulation by Derivative Developers. The company had a good earnings report on August 15th. This is NOT an all-time high. A shift to a platform or sideways trend would be ideal to reset for the next swing-style run. Chaikin Osc is overextended and floating as oscillators tend to do. Sideways trends pattern that out rather quickly most of the time.
