One afternoon a stockbroker was cold calling potential clients about a stock and found a taker. "I think this one will really fly said the broker. It's currently only trading at $1 a share."

"Buy me 1000 shares," said the client. The next day the stock had jumped to $2. The client called the broker and said, "You were right about that stock, I'd like to buy 5000 more shares."

The following day the client looked in the paper and the stock had skyrocketed to $4. The client ran to the phone and called the broker, "Get me 10,000 more shares," said the client.

"Wonderful!" said the broker. The following day the client looked in the paper and the stock had reached $9.

Deciding to take advantage of the huge profit he had made in just a few days, the client ran to the phone and told the broker, "Sell all my shares!" The broker said, "To who? You were the only one buying that stock."
