If I understand correctly:

> we still make a small profit on low oil prices.

and

> when prices are low everybody expects to rise back to what we're used to again soon, because we're naturally optimistic. But that's not a law written in stone, it might be true that oil prices drop again in future, so we're better off selling it today.

So basically, a bird in the hand is worth two in the bush.
