The top two are US small cap biotechs and can be volatile, (as volatile as a Chinese small cap) but both with forward events this month that should push them much higher. And they're good for long term (IMO) also.
An excellent, active, and highly-followed board for biotech stocks with multiple "baggers" recently is here at "$heff's $tation":
Look at TARM, a jr miner that should break out in the next 6-12 mos. Currently at $1.10, a 3-5 bagger in that time frame. A Yamana JV deal expected in the next 1-2 weeks should give it a pop. Revenue production in Q3 on just 70M shares. GL
