Liquidity refers to the quantity of tradable goods and services in the market within a certain period of time. It reflects the supply and demand situation in the market and is one of the important factors that determine price fluctuations. If there is a surplus of liquidity, prices will fall; if there is a shortage of liquidity, prices will rise.

The change of liquidity has an important impact on prices. When liquidity increases, the supply in the market increases, which may lead to a decline in prices; when liquidity decreases, the supply in the market decreases, which may lead to an increase in prices. Therefore, the change of liquidity can be an important basis for investors to judge the market trend.

In the stock market, liquidity is also one of the factors that investors must consider. If the liquidity of a stock is large, its price fluctuations may be more剧烈; if the liquidity of a stock is small, its price fluctuations may be more stable. Therefore, investors consider the size of the liquidity when selecting stocks to avoid investment risks.

In summary, liquidity refers to the quantity of tradable goods and services in the market and is one of the important factors that determine price fluctuations. Investors should fully consider the change of liquidity to better grasp market trends and make more informed investment decisions.
