"This book is written for the purpose of giving our clients some ideas of the fundamental principles that guide us when we select stocks for them to buy, but these principles are valuable to every person who trades in listed stocks or in any other kind of speculative stocks. First of all, we want you to get a clear conception of the meaning of the word speculation, which is explained in the next chapter. Our purpose is to protect you against losses as well as to enable you to make profits, and it is very important that you understand how to provide for safety in your speculating. It is a well known fact that there are tremendous losses in stock speculation, but we claim that almost all of these losses would be avoided if all speculators were guided by the principles expounded in this book.
