I think something that is important with SFRX it that unnamed family continues to buy as reported in either annual or quarterly reports. They buy a lot. Millions of shares but restricted so they can't easily or quickly be sold.
Also, SFRX just filed an SC 13D yesterday indicating that an "insider" (a Kennedy) bought shares on the open market. Must be immediate family like his wife, I'm not sure who qualifies to require a 13D. Not a lot, 200,000 shares, but since Kyle doesn't draw a salary from SFRX I don't imagine he has a lot of money to spare. He also has never sold any of his own shares so no income source there either. I don't remember an SC 13D ever being filed before so that is good news.
That's what I consider real information.
