The company has a P/E ratio of 3.8, equal to the average chemicals industry P/E ratio and below the S&P 500 P/E ratio of 16.6. TheStreet Ratings rates Gulf as a hold. The company's strengths can be seen in multiple areas, such as its robust revenue growth, largely solid financial position with reasonable debt levels by most measures and impressive record of earnings per share growth. However, as a counter to these strengths, we find that the stock has had a generally disappointing performance in the past year. You can view the full Gulf Ratings Report.
