If was looking for an investment, I might look into buying oil futures, when it was high, some experts said the supply/demand price for it should have been around $70. That is probably still the case.
At the pump prices haven't dropped as much here, for some reason. It is refined within the state, so don't know why it has been slower to come down. I paid $2.30 last fillup for gas. Diesel was still over $4.
It means 4-5 billion less revenue for the state govt here, but not a deficit. There is plenty in savings.
I was buying some silver coins last spring when it was up to $17., and they were lagging behind the bullion price. I see it is now around $11.,and gold is down also, it looked like it was going to break $1,000.
