NEW YORK (TheStreet) -- The S&P 500 slid 0.85% on Monday, but the CNBC "Fast Money" traders were more focused on West Texas Intermediate crude oil. The commodity climbed 6.35% on the day and is now up 27% over the past three trading sessions. Investors should not be short oil right now, given the strength of the current rally, according to Guy Adami, managing director of stockmonster.com.
