You couldn't be more wrong! As an economics student i have heard time and time again people totally misunderstand how the market works.

There is no such thing as 'risk' when buying shares. There is however 'uncertainty'. You're saying, that when someone buys shares in a company they should just pick one at random as it's all based on luck? Nonesense! People research and follow companies to pick which one they think will perform well. Of course they can't guarantee their investment will pay off; they are uncertain

If shareholders were given misleading information, then they have every right to launch a class action. I don't think they'll win though; unless some pretty revealing evidence is disclosed that we have been unaware of
