TheStreet Ratings team rates BILL BARRETT CORP as a Sell with a ratings score of D. TheStreet Ratings Team has this to say about their recommendation:

"We rate BILL BARRETT CORP (BBG) a SELL. This is driven by a number of negative factors, which we believe should have a greater impact than any strengths, and could make it more difficult for investors to achieve positive results compared to most of the stocks we cover. The company's weaknesses can be seen in multiple areas, such as its generally disappointing historical performance in the stock itself and weak operating cash flow."
