Standard Bank Group vs Barclays Africa Group
The chart considered is that of Standard Bank (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 (Standard Bank) has been underperforming security 2 (Barclays Africa). Bollinger Bands have been added to the RSC and highlight the underperformance of security 1 reaching abnormality 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 Standard Bank Africa, short Barclays Africa.
The target from the technical indications would be for the RSC to move back towards the 20MA (red line) which is regarded as the mean. This could occur with the price movements of the securities in a number of ways:
- Standard Bank rising and Barclays Africa falling
- Standard Bank rising faster than Barclays Africa rising
- Standard Bank falling slower than Barclays Africa falling
Should one of these scenarios play out successfully the expectation would be for a net gain of 3.3%. A stop-loss would be considered equal to the anticipated gain of 3.3%.
