Market capitalization-to-GDP ratio is a financial metric that compares the total value of a country's publicly listed companies (market capitalization) to its gross domestic product (GDP). It is a measure of the size of a country's stock market in relation to its overall economy. A high market capitalization-to-GDP ratio indicates that a country's stock market is relatively large compared to its economy, while a low ratio suggests that the stock market is relatively small. The market capitalization-to-GDP ratio is often used as an indicator of a country's overall economic health and can provide insights into the level of investor confidence in the stock market and the broader economy. A high market capitalization-to-GDP ratio may indicate a thriving stock market and a healthy economy, while a low ratio may suggest a less developed stock market and weaker economic conditions.
