When stock prices in general are falling (not just the price of some specific stock) that is called a bear market; in comparison, when stock prices in general are rising, that is called a bull market.

That is why a bull symbolizes upward motion and a bear symbolizes downward motion. Even stock brokers are sometimes capable of humor.
