Yahoo is frequently wrong with their charts and other information. Sometimes they get it right, but not all that frequently recently. Not sure why they pick out KOG to mess with. I am on Yahoo 7 days a week and usually 5-8 hours per day, so I am very familiar with KOG trading as I get information from other sources on a regular basis too. KOG is a terrific stock. Get in on the boom and you won't regret it in a few months....a few years!
