I'm one of those longs. I made a lot of money in ACI in 2010-2011, and sold in the low 30s in early 2011. When the price dropped into the low 20s, I bought back in, and bought more at 13. I'm tempted to go to the well a third time and buy more at 7, but it violates my "rules" to tie up too much in one stock. I think the best we can hope for tomorrow is a more optimistic outlook from ACI; that should limit the downside.
