Piper Jaffray analyst Matt O'Brien recommends using the post-earnings weakness in shares of Cooper Companies as a buying opportunity. The company's guidance for fiscal 2020 is below Street estimates but the sales outlook is management's typical conservative view out of the gate and the earnings shortfall is completely explainable due to heightened spending on MiSight, which was approved ahead of schedule, O'Brien tells investors in a research note. The analyst lowered his price target for the shares to $344 from $360 and reiterates an Overweight rating on Cooper Companies.
