SFMI moving from multiples to a fraction of GHDC had little to do with market perception, and everything to do with the use of SFMI shares to finance both SFMI and GHDC. The relentless selloff by Iliad each month was obvious. SFMI shares were used to pay everyone from PQ to contractors. And when GHDC needed to pay PQ and family their "other" undeserved salaries, did they issue GHDC shares to pay them? Of course not! SFMI issued shares to loan to GHDC to pay their employees (I refuse to use the term "workers"). So GHDC actually owes SFMI money according to the latest filings.
I don't know how this will affect the ultimate value of each stock other than SFMI being much more diluted than GHDC. But I do think that SFMI stands to move quickly if good news arrives and the dilution stops, especially if more buying comes in. Whether it will be able to catch up with or even pass GHDC will depend on the news we get, but I expect both to move up.
