Karin,
In all honesty, I have no idea why people would sell at eight, because I'm a long, I'm sure we'll have a selloff at 10 and so on.
So even though it's fun to watch I think our best days are ahead of us and I plan on sticking around for at least a year.
I only accumulate, because when I've tried to flip for more shares I always end up chasing the stock. So I look for the bottom (or what I perceive is the bottom) and accumulate more stock. Val :-)
