When you analyze correlation, you need to understand what's affecting each coefficient. It's easy to make the assumption that that is A goes down and B goes down together that B is going down "because" of A. There are actually endless variables inbetween A and B you are not accounting for that could be driving what you think is the correlation. For example, when oil prices go down, sentiment about oil might go down. When sentiment goes down, price goes down. But what are all the variables driving sentiment. It's probably not just price.
Simply looking at a correlation is not sufficient. And trading on that correlation is criminal. When looking at data, it's not the absolute value you are concerned about, but rather what is driving that value. Quantitative finance exists for a reason.![]()
I may be stupid, but I'm not that stupid. And there's certainly a lot of people that's more stupid than me in this world.
What you're saying here is merely statistics 101, i. e., correlation does not imply causation.
I'm merely curious about the correlation between the oil price and oil stocks. I've heard of more crazy assumptions than this and I didn't say I was interested in using correlation alone as a trade idea. Still interested to know where you get close to zero correlation from.
