“A piece of property is worth as much as someone is willing to pay you for it. So it is with common stock. Find stocks for which you think someone will be willing to pay you a higher price at some time in the future. This approach is applicable to any type of investment—in a diamond, a painting, a bushel of corn or wheat, a house, a piece of land, or a share of common stock. The market price of the item reflects the psychological factors—the extremes of optimism and pessimism—that can cause the value of an item to vary widely, sometimes in just a few hours or days. When the market value of an item is plummeting, it reveals that the fear many people have of lower values for their property is stronger than their hopes for higher prices.”
