Since 08/2009 to 07/2010 C has been trading from $3.59 to $5.43. By the uncertainty in today's market I have seen much worse than this. Certainly a lot of investors have made a lot of money on these trends. Most of the markets have been down for the past 10 sessions and C has held its ground considering the mass amount that the Gov. is dumping. Look at the charts and see what a profitable opportunity C is. If you expect to buy today at $4 and sell tomorrow at $8 you need to give up trading, the idea is to buy on dips and sell on resistance. C will not stay at $4 for much longer as the shares the Gov. owns will become less with time. Nobody can say for sure how much it will be in a month but by the ground it held these past sessios it will past the $4 a share.
