"We remain optimistic over the near-term outlook for the refining sector ahead of heavy seasonal maintenance and the shift from winter to summer grade gasoline," Bank of America Merrill Lynch analysts wrote in a Feb. 15 report. "Alongside Superior's access to advantaged crude, CLMT should benefit, but their hedged approach leads them more likely to underperform the more volatile 'pure plays', where exposure to margin volatility is intact. Accordingly, versus the largecap independent refining sector, we maintain our Neutral. We have updated our model following the 4Q results. Our PO moves up to $24, given higher distributable cash flow than expected."
