Stephens analyst Justin Long nots that CSX just issued a press release revising its 2017 OR and EPS guidance due to various operating challenges in July and August. On the positive side, CSX reiterated its 2017 guidance for free cash flow, service metrics are returning to normal and many of the operational challenges are behind them, the analyst notes. Long says this guidance revision does not come as a major surprise given the company's well publicized operational challenges in Q3. He reiterates an Overweight rating and $61 price target on the shares.
