I think some people just get really excited when they see the price go up they assume it will always continue to. I'm hoping to see .075 or so...but .10 would require it to double relatively quickly.
edit: And for all we know the spike today is from someone on this board buying in. I think that happens a lot on IH...people talk about how great stock is...buy some shares to pump it, then get everyone else on the board to buy in.
