All the dd i did on this company led me to believe

All the dd i did on this company led me to believe that this was going to be an outstanding investment. So much so that i invested $600k.....which is now down over 500k. I knew better but believed in the data. I don't know what to believe anymore. All these damn delays and the vanilla Hirsch letter hasn't helped. As they say...you only have a loss when you sell. Have no choice now but to wait it out and hope for good news soon.
