The S&P 500 Index is a popular stock market index that measures the performance of 500 large companies listed on stock exchanges in the United States. It is widely used as a benchmark for the overall performance of the U.S. stock market. While the S&P 500 Index focuses on U.S. companies, there are similar indices around the world that track the performance of companies in different countries. One such index is the Tel Aviv 25 Index, which includes the 25 largest and most liquid stocks listed on the Tel Aviv Stock Exchange in Israel.
