So a fun one that has been paying off for me lately is CBIS. Bought a few weeks ago at 0.01 and it is at 0.07 right now.
Looks like the legalization of cannabis oil is passing in California and that is making this stock jump. All of my latest buys have been in this same area, I just have a feeling that this is a great market and can only grow from here.
Another couple I am watching it batteries and lithium - as well as fire suppression systems (due to the advancement of lithium use).
