Systemic fluctuations are usually related to macroeconomic factors such as changes in interest rates, inflation rates, and adjustments in government policies. These factors affect the entire market, leading to the majority of prices moving in the same direction. For example, when the central bank raises interest rates, it may suppress economic growth, resulting in an overall decline; conversely, lowering interest rates may stimulate the economy and drive the stock market up. Government fiscal policies, such as tax adjustments and government spending, also have significant impacts. Additionally, the release of macroeconomic data, such as GDP growth and unemployment rates, can trigger fluctuations. When economic growth is strong and corporate profit expectations rise, prices tend to increase; conversely, during an economic recession, prices may decline.
