Take a look at the WTI and Brent crude oil prices after OPEC

Comments from OPEC producers Iran and Iraq suggest that the output increase may fall short of the one million bpd target and may only realize a range of 500,000 to 770,000 bpd, as some countries would find difficulty in hitting the new quotas.

The US crude benchmark, WTI, rose more than 5% in the immediate aftermath of the increase announcement. The Brent crude benchmark managed to add 3.5% on the day. The gains were then pared.

Trade idea based on relationship between Brent and WTI crude oil benchmarks

Rather than looking at trading a purely one direction bias in the oil markets, the relationship between WTI and Brent might be deviating enough to offer a market neutral or pair trading opportunity.

The below chart looks to help identify this potential opportunity.

Brent Crude vs US Crude (WTI)

The chart is the Brent candlestick with a relative strength comparison (RSC) indicator added. The RSC (blue line) compares the price of one security with that of another in a ratio format.  The RSC has experienced a decline in value recently, which highlights that security 1 (Brent) has been underperforming security 2 (WTI). Bollinger bands have been added to the RSC and highlight the underperformance of security 1 relative to the usual relationship of the two securities.

It is expected that the relationship between the two securities will revert back to normality favouring a possible pair trade opportunity i.e. long Brent and short WTI. The target from the technical persepective would be for the RSC to move back towards the 20 moving average (red line) which is regarded as the mean. This could occur with the price movements of the securities in a number of ways;

1. Brent rising and WTI falling
2. Brent rising faster than WTI rising
3. Brent falling slower than WTI falling

Should one of these scenarios play out successfully, the expectation would be for a net gain of 4.4%. A stop-loss would be considered equal to the anticipated gain of 4.4%.
