Market performance refers to how well a financial market, such as a stock market, is doing over a specific period. It is often measured by the changes in the prices of securities, such as stocks and bonds, and can indicate the overall health of the economy. Key indicators include market indices like the S&P 500 or Dow Jones Industrial Average, which track the performance of a selected group of stocks. Investors and analysts use market performance to make informed decisions about buying or selling assets. Positive market performance typically suggests investor confidence and economic growth, while negative performance may indicate economic challenges or uncertainty. Understanding these trends helps individuals and businesses navigate their financial strategies effectively.
