Citi anlayst Robert Morris says his firm's reduced 2018 WTI forecast to $50 per barrel from $57 and longer-term forecast to $60 per barrel from $65 has a "significant impact" on 2018 estimates and net asset values for his Exploration & Production names. Based primarily on valuation, Morris downgraded Canadian Natural (CNQ) and EOG Resources (EOG) to Neutral from Buy as well as EP Energy (EPE) and Occidental Petroleum (OXY) to Sell from Neutral. He cut his price target for Canadian Natural to $33 from $40, for EOG to $98 from $112, for EP to $3 from $4 and for Occidental to $58 from $66.
