You are just shooting names now, all great investors but none of them has any mathematical model we could use here.
The Buffet philosophy is not applicable since Tri-way has not proven large scale operational results. Berkshire does simply not invest in unproven enterprises, so Buffet is completely irrelevant trying to value Tri-way. Buffet is the type of investor who will buy Tri-way when the Tri-way share price has reach $100.
Have never seen any mathematical model by Fisher, however I like his investment style, definitiv applicable to SIAF
Never seen any model by Lynch...
The only reason I used Graham is because that is the only model I know of that only focus on the future, not the past.
