Bull market is a period of financial assets when prices are rising or the expectation of price increase is high. During this period, the prices of financial instruments rise, and investors tend to make purchases. The emergence of a bull market is generally associated with factors such as economic growth, low unemployment rates, and high profit margins. However, it should be remembered that a bull market will not continue indefinitely and there is always a risk of decline. Therefore, investors should also maintain a balanced portfolio and reduce risks during bull market periods.
