This is just getting stupid now
So a purchase of less than 0.01% in a company is enough to linearly extrapolate that it's value has increased by ~$20bn this year? Come on now, I'm sure those little things called reality and common sense are around here somewhere.
I expect that the boy Zuckerberg or anyone else with a substantial share holding could quite easily give away a few million dollars of pocket change to investment firms to fund them buying some shares at ridiculous prices and still make a ludicrous profit on their existing shares. As it's a private company and therefore outside of the usual SEC regulation, the potential for manipulation makes this sort of speculation laughable.
The scary part is that when/if they do actually float it, the markets will probably have turned these sorts of stunts into a self-fulfilling prophecy, unless the house of cards has already come crashing down by then. Wouldn't want to be holding those shares when the shit starts hitting the fan.
I'm off to trade 0.0000001% ownership of my company for a pint. I guess that'll make it worth about £3.5bn won't it?
