I agree with hearing the manipulation excuse. Been on here for years, and everytime it goes up, it's due to a great company. When it goes down, it's never the fault of Corning - it's some manipulation whine.
Maybe the MM's can effect this for a few pennies and for a few hours, but to blame the MM's for a $10 drop is BS.
Think GLW got bidded up too high and now getting slammed too hard. The true price is somewhere in the low to mid 20's, IMHO.
FORGETABOUTIT: no asshole I totally disagree with your valuation. In the future if your going to make a statement about valuation, substantiate it. There are to many assholes on this board who make statements without facts.
