Well, I do not. And of course, it's just not that simple anyway. The ticker changes are often done to cover tracks, but that's not all. CEO changes are just as common. They do this to get out of a hot situation, but the real reason I surmise is to dump all their restricted shares into the float. Technically anyone that is on management is not allowed to sell more that 1% of their shares per year (something like that) if a company is not current in their reports. BUT, if the person resigns, then they can sell them all in 90 days. Kinda explains the CEO merry-go-round.
