Nitin Kumar and Carley Garner break down Occidental Petroleum (OXY) selling OxyChem to Berkshire Hathaway. Nitin thinks this frees up OXY’s balance sheet and will allow them to start stock buybacks like their peers. Carley calls it “opportune timing,” since crude oil tends to peak in October. She considers crude’s path a slow motion train wreck this year and has her eyes on “50 and below.”
