Over 3 million shares and SFMI goes down. So your measley 13,000 shares of SFMI would have had 0 affect on the pps.
Now on the other hand, if you added your 13,000 measley shares to GHDC from the 92,000 shares traded today, you would have brought it higher from the +13% increase it had today.
Focus on Silver Falcon's progress BUT GHDC's stock.
