Pair Trade - Short CNQ and Long XLEThis is a pair trade idea based on CNQ/XLE pair cointegration. My calculations show that these two stocks diverged by more than 2 standard deviation and, based on mean reversion, should come back to mean. This pair's rolling mean is 28.3 over the last 280 trading sessions. The current value is 23.6 and one standard deviation is 1.8. The trad can be done by shorting CNQ and going long XLE in the proportion calculated through beta. Alternatively, it can be entered as two credit spreads - bear call spread on CNQ and bull put spread on XLE. This is how I will be entering this trade on Monday when the market opens - $CNQ $22/$24 Feb 21 bear call spread for $0.5 cr and $XLE $57/$55 Feb 21 bear put spread for $0.6 cr. Will be watching the bear call side and adjust if necessary.
