TheStreet Ratings team rates PUBLIC SERVICE ENTRP GRP INC as a Buy with a ratings score of B. The team has this to say about their recommendation:
"We rate PUBLIC SERVICE ENTRP GRP INC (PEG) a BUY. This is driven by some important positives, which we believe should have a greater impact than any weaknesses, and should give investors a better performance opportunity than most stocks we cover. The company's strengths can be seen in multiple areas, such as its revenue growth, expanding profit margins, good cash flow from operations, increase in stock price during the past year and growth in earnings per share. We feel these strengths outweigh the fact that the company has had generally high debt management risk by most measures that we evaluated."
