In theory if they are the most arrogant guys on the world and wait till the final day of forced cover... hm then we can run thousands of % in one day :-)
I've been in a stock that started the day a 2 cents and ended the day at 25 bucks, but this was pre-Monk. Happened once, a biotech posted right before market opening that the FDA had approved their product for sale. CDIV could potentially do that as well. Sell orders are already in the 30s.
