Filtering OP Movements26 Mar 2021 09:25
I find it useful to filter out the variations in sp which seem to be due to movements in OP. This is not a precise art and it inevitably requires adjustment from time to time but my current formula, which has worked for me over the last month is:
Nominal Sp = 1280p for Brent at $59 +/- 22p per $1 variation in Brent
At $63 Brent, for example, this would estimate RDS as nominally 1368
For me, the difference between this calculated ‘nominal’ and actual sp serves as an indication of how strongly RDS is actually performing.
