First if you are going to listen to people on an investment board read up on their prior posts and predictions.
If you dont need the money I personally would try to hold hold this long term. You're young let it ride. In the meantime read up about the company learn to read its balance sheet, or even the results of their prior trials, upcoming ones and their pipelines.
Not many people get lucky enough to have the first biotech they invest in get approved. So instead of just the money you can make on it think of it as providing you a great educational experience as well, that you're you're getting paid to learn about.
Who knows 20 years from now we might read the story about how you became the next investment wiz, or better yet helped find a cure for a disease.
Seriously, try and hold on to this stock as it should rise higher over the next few months. Remember you will have to pay taxes on any gains, so make sure you set aside enough money if you decide to sell. I'm not sure why people are reading he bought $100 of stock, its 100 shares #$%$30, so $530 plus commission.
lol....good thing its only 100 bucks, next time never buy on the news.....when you are buying , people are selling. See why the price is up only 1.6 ....because people are selling the news! profit taking.
