Cramer has only been positive on integrated oil Exxon Mobil (XOM) since late 2006, when crude oil continued its undeniable run to 75 dollars per barrel and carried oil and oil service stocks with it. He had previously called XOM the worst integrated oil, referring viewers instead to best of breed name ConocoPhillips (COP). In a 2/2/2006 lightning round, Cramer said of XOM, "That's just a large bank masquerading as an oil company. They have not kept up with reserve growth." He consistently referred viewers to drillers such as Halliburton (HAL). More recently, though, he has been consistently bullish in 2007. In the main segment of the 11/29/2006 Mad Money show, he claimed, "XOM is the worst of the big oils," but called it a stock that has been annointed by mutual funds as a must own holding, and gave it a 100 dollar price target. "Some mutual funds decided to buy it and they won't stop buying it until they're finished setting up their massive positions"..."Catch the most miraculously irrational rally I've ever seen."
