Yep and what a lot of people do (including me) is have a hold parcel and a trade parcel so you have the best of both worlds and spread your risk. Of Course this only works if you invest a certain amount of money to offset the trading costs. So I have for example a total trade with a minimum of $5000 Than I have $2500 to hold and $2500 to trade. I also have a stop loss in place on paper that I trade the next trading day If the price falls under that. Announcements rarely make the price jump to the extend that you can't buy back in the next day, if that happens be really really care full for example have a look at SCU that went up 3000% in one day last week, see where it is now.
