TheStreet Ratings team rates PG&E CORP as a Buy with a ratings score of B+. TheStreet Ratings Team has this to say about their recommendation:
"We rate PG&E CORP (PCG) a BUY. This is driven by a number of strengths, 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 and largely solid financial position with reasonable debt levels by most measures. We feel these strengths outweigh the fact that the company has had sub par growth in net income."
