Nice 800% gain there! You've found the hot penny sector for sure. I see why you are looking for news sources so you can spot MMJ tickers as news announcements are made. I have a list of 104 MMJ tickers now. It seems the initial announcement has the most momentum of pps UPtrend within 1-2 days and then a trader must gamble on holding past that initial momo.
I can name a few MMJ tickers that are continuing an UPtrend since the industry's main news in January. I'm still working on the news links...
