Broker recommendations for AMI, JIN and FBR

I am amazed that I have 3 big parcels in 'unrated' stocks, that is, they are ignored by brokers.  They don't do any research on them according to CommSec.

These are JIN, AMI and FBR.  My early buys on JIN and AMI have more than doubled in value.  That made me reluctant to top up as the share price had jumped so much.  But I did top up recently and still doing well! 

However, it dropped the overall rise to under 100% for JIN but still over 238% for AMI. 

FBR has been all over the place but the prospect looks extremely bright again.  After ditching Caterpillar or is it the other way around, the share price plunged.  That gave me a good opportunity to top up again.
