There's not a website dedicated to publishing Abbreviated New Drug Applications (ANDA). At least not that I know of. The US FDA does not publish it. However, there are court records to indicate so but who's going to research that.
News and announcements are the key. When a pharma co. make a significant stride in a drug development be it generic or phase I, II, III trials, there will be an announcement. Stock runs tend to follow the news yet astute investors plan their move around the announcements.
Actually, Cafe Pharma website does a good job of linking many pharma related news on their website.
You can't possibly read and research all there's to research pharma stocks...I guess you could if you were a day trader and that's all you did.
I try to follow 2 to 3 stocks at a time. And time to time I post about them here... as I posted about MNTA 4 times previously. Last Monday, I posted about ARNA which gained 20%. I have bought and sold since. But I'll be following ARNA closely.
I'm sure there are services that does biopharm forecasting...but I don't know of any. But it helps to understand the pharma consumer market demands before making your investment decisions.
You also need to decide how to invest long term vs. short term. Alot of it is a gamble... but at least, it's an educated gamble with a higher chance of winning than a blackjack table in Vegas.
