a basically sound company with an expectations , news, ramp driven stock price .
also many lost a bundle in the late '90's when it touched $7 with hopes of $12 but then fell out of the sky, so are trading up , hopefully .
if you have the time to watch carefully and a wad to play with you can as you surmise do nicely on small profits large turnover . good luck but keep a core bundle for the big one
