I'm comfortable with my diligence. Based on diligence, bought shares in Dec / Jan that are up 50%. Had some from before and have added during the last few weeks.
This opportunity is "not too good to be true" -- rather, it looks to be a case of info arbitrage --- it's hard to connect all the pieces without spending lots of hours -- so stock trades at a discount to value.
When news of investigation results hit - it will be easy to connect the dots of value - so stock will go up based on easier access to info (and its value).
Happy to get a 4x + return - simply based on doing a little research. Looking forward to that and the additional 4x return -- as the company normalizes at value point for clean chinese company in an emerging field...
