ie: spoo = cash (@ exp)
I understand this. By why today? Why not tomorrow or on Monday? Is this just the way it is, or is there a better explanation? Although there was a gradual decline in volume leading up to today, the Thursday the week before expiration always shows a HUGE decline. I was just trying to see if there was a more specific explanation.
