Further to above post re:slow brains.
Share prices ARE subjective, and are determined in any free market by anticipated growth/current growth/how much you like company/is it worth a gamble/ etc..etc... I could go on. Some people may even buy shares in a particular company because they like the stationery. Daft, but true.
So, Whilst the current market capitalisation is a fact (which I don't deny), that value is based on the perception of all participating players in the given market. By its nature, IT IS A VERY SUBJECTIVE VALUATION. Ask two stockbrokers and they often give differing assessments for the same business.
As I have said before, it does not mean the business will be profitable or even exist a year from now. ( I should point out this is not a desire for ryanair or any airline to go under, just a fact).
. .To try to claim that Ryanair is Europe's biggest airline, is like trying to claim that BA is the world's favourite airline.
