When the cow is crazy, it runs all the way with its head down and its horns facing each other. In ancient times, they were described as bullish. When most buyers are optimistic about the stock market and have invested a lot of money, then the stock market will rise all the way. The K-line chart looks like a bull running down all the way and rising all the way. So it is called a bull market.

Bears always walk slowly. They hibernate for several months. When there are too many bad news in the stock market, such as raising interest rates, a large number of buyers are bearish, and a large number of funds are withdrawn from the stock market, then the stock market fluctuates up and down at a horizontal level, hardly rising or rising very slowly, just like a bear hibernating, so this situation is called a bear market.
