Redbacka referred to breakdown in correlation for the purposes of market timing i.e. short duration. This context is important.

You cannot change x/y axes & you cannot look at indices over long time periods(12 months) and pull percentages to signify correlation. Not how things work.

The gold vs pigs chart is meant to prove that, just coz the lines look like they follow each other after (manipulating the x/y axes), it does not mean the instruments are correlated. The approach is flawed. I don't have to prove that IG is cheating (btw they're not cheating, it's a 'feature' in the software and it's flawed - bloomberg terminal does the same, you have to disable it as does tradingview and few others).

I will pull my cross asset correlation sheet from goldman/deutshe and post it here later, after market.
