Buy at the end of the day, then sell on the next, right after the opening bell. (But just do it with spare "trading cash," otherwise you might get caught outside when she goes back up. (JMHO)
I have never seen a stock behave quite like this one. A $20 stock that has a daily fluctuation of $1/share up, down, or up then down, or down and then up. I am not a trader, but if I were, I could not even begin to figure out how to play this stock. I am just going to hold and hope for $30, my sell target.
