This is a good news . 
But again , news is irrelevant to the grand scheme of things . 
When 100 ordinary small investors see the chance to buy in early , 1 major player will see the chance of dumping earlier .  It's always about the trend , not about the news . When the major player is not on a dumping trend , the price will go up with good news . On the other hand , if he is on a dumping trend , the good news will cover him . 
So control your risks , think carefully before you buy in . 
Anyway , I'm buying , but I expect things may not turn out positive to the price after all . 
(Facts I know personally :  Every good news last year covered a big guy dumped his BTS to buy stocks in China  .  The announcement of big thing 1.0 gave him the chance to dump more than 1 million USD within a week . And BTS was in a downward trend ever since , even before the merger ) 
So if you are looking for short term profit , learn some trading skills before you rush in . 
If you're looking for long term investment , then .....why do you buy in after a good news ?
