This means that the buyer of a stock only deposits with his broker a
small part of the value of the shares he is buying or selling. He is
simply gambling, and very hazardous gambling it is. If he guesses
wrong, he must pay up more and more margin or lose altogether. Dealing
on margin is the favorite sport of the "lambs," and it is very
profitable, indeed, to those who take advantage of their misfortunes.
The odds are all against the speculator on margin, and sooner or later
his money disappears and he disappears with it.
