CWTR has the most upside of the three. Multi-bagger potential. CEO spent millions buying at this level and above. But it's too risky for me. They probably won't go bankrupt, but it's no sure thing.
I own nwy and cach. I think nwy has the most upside of these two. I'm loaded with cach, so may pare back some if it continues into the $7's. Though I think it could double if the economy keeps recovering - it traded in the teens for years. Nwy is another potential double or more, imho.
