Good point, but as someone else said I think (and I could be wrong) the share price isn't the 'real' value of these types of companies. Value would be in future earnings potential / complement to their existing business. If company xyz wants to pay 10-20x the current share price of company abc they must believe its a good long-term investment. At the end of the day we can all be right or at least be respectful enough to hear each other out.
