As previously reported, Credit Suisse analyst Betty Jiang upgraded Whiting Petroleum to Outperform from Neutral. The analyst noted that under Brad Holly's leadership over the last year, the company has demonstrated consistent execution as the company met production targets at lower than expected costs and stayed on budget. Whiting Petroleum still has to manage around known legacy issues, including a declining Redtail production base and inventory depth in the Bakken core, both are reasons that they trade at a discount valuation, she contends. But Jiang points out that management is staying on message with the company's core value proposition to investors, namely balancing growth with meaningful free cash flow generation.
