Each time the predictions come true and you begin to trust the mysterious company that keeps sending them to you. You may even start to feel a little special that you have been singled out to receive this highly valuable market information. You would now rather forget, you have invested all your savings in the company and you never received another letter, or saw your hard-earned money again.
You go and share your misfortune with a close friend and find out that he too received the same letter, only his letters stopped arriving after the second month. He tells you that the first letter was correct in its predictions, while the second one was wrong. It didn't take you very long to figure out what happened.
