After the spinoff of CVG, CSN should do a 1 for 2 reverse split: instead of 100 shares @ $14 = $1,400 you would have 50 shares @ $28 = $1,400. When shares are priced as low as CSN will be after the split problems can result: margin issues, etc. Using a reverse split to avoid them would make sense.
Reverse splits are most common for stocks that threaten to become low=priced "penny stocks." CSN can actually benefit from its reduced price (saw it today in NY Times trading as "wi" (when issued)giving it room to "get back to where it belongs." That concept doesn't necessarily make sense as far as real value is concerned, but who needs "real value" in this wacko market. Maybe CSN should just change its name to csn.com and rake in the big bucks.
