Take the time to understand who's involved with a company and such, not the bios written by themselves, but their past involvements.
Take a look at business handlings and results (in filings). GRBG management make fat salaries (6 figures) and made a plethora of acquisitions, some very questionable imo.
Take a look at share structure. The preferred to common conversion isn't a 1:1 ratio. Also, O/S has gone up 100 million this past month. There has been no updated filing indicating shares have been sold/registered (Form D).
There is more, I kinda talk about the other side of the coin here. PRs are fairly easy to write, effective business execution is time consuming and hard work.
Good luck
