Oh there is! For instance, I bought a 100M share of PFI some time ago, but I would have to ask for 200M for it now, if you were to buy it, cause of the latest contracts that PFI has signed, which have risen the value of it's shares.
Whats the use of keeping shares? Do we get some credits? however if you bought a share for 100 million. they should pay you 10 million per month I think
