Doesn't that graph kinda prove my point? Outside of the "All industries" a lot of groups have bigger profit margins... including things like food industries... which is... well food.
Though i do believe it's actually around 11-12% now... and just average for the S&P 500.
The reason it's higher is because Oil and Gas companies store gas.
If they didn't, and a big stop in production happened they'd be screwed, with how screwed up a lot of the areas with gas are... this can be a worry.
As such when gas is cheap... they tend to buy a lot more then they need and just let it sit in tanks.
Then when gas is more expensive. They buy less and let some gas out of their stores back when it was cheap.
Just how oil speculators work. Or atleast that's how it works to the best of my knowledge.
