In the good old days, we said "not enough information".
That excuse, is no longer the truth. It is a stupid excuse.
All information about companies published on the internet in governemnt webiste. All economic statistics are published. We all have access to the "trading floor" of stock exchange thanks to Internet and the latest trading softwares. We all can have access to all the news that is travelling around the world e.g. by Reuters.
Reading blogs, working with social networking websites, we can be directly exchange e-mails, chat or whatever with major leaders of companies or their friends.
Not enough information? Wow! The guy must be blind or stupid or what? The problem is what informatin to use from the sea of data?
