[填空题]Graham Paterson

[单项选择]
Benjamin Graham was a noted economist who formulated his theories on stock market investment in response to the great stock market collapse of 1929. Specifically, he viewed the collapse of the stock market as a result of people following market trends too closely. In fact, he often used a character called "Mr. Market" in his works to demonstrate how foolish it was to simply fall into line with market trends. If a person called "Mr. Market" appeared on your doorstep each day and offered random prices for various stocks, you would not accept every offer he made, since some of those offers would be utterly ridiculous. Instead, Benjamin Graham argued, a person who wishes to do well in the stock market should seek out stocks that are being sold for less than their value should be in a rational market. This was something he called value investing. The problem, of course, lies in figuring out what a stock’s ideal value should be.
A. worth.
B. company.
C. book value.
D. theory.
