After the market close today it's interesting to look at the final prices on this day of Kodak's big inkjet printer announcement. There's an old saying on Wall Street that goes "buy on the rumor and sell on the news" which should mean we should have seen a dip in Kodak (Eastman Kodak Inc) shares today, everything else equal (i.e. a fairly flat market, which we had). Well, EK had a nice bump, and HP (NYSE HPQ) and Lexmark Corp (LXK) dropped a bit. OF COURSE, let's not get too carried away with one day's market action!
