I think it's more than a couple. I said this yesterday and I'm gonna repeat it today, I think someone went and say Wolf of Wall Street this weekend and decided it would be a good idea to get a handful of friends to buy up shares for them. When that worked, I think they gathered a larger group of friends, sold off a ton of shares so the newcomers could buy in at a lower price, and ran it all over again.
The bouncing sure seems to support that, but then a lot of stocks do that, as well; usually not pennies that have been dormant for months, though. I posit that the first round "traders" have a hold time on funds from sell orders that whoever's behind this wasn't aware of and will be back in the market Monday.
Either way, I'm probably getting out on Friday unless this thing drops through the floor again, but it'll be fun to watch, at any rate.
