Buffett indicator

Ratio between a country's total market capitalization and GDP to value the stock market.

The Buffett indicator, named after the investor Warren Buffett, is a key figure for assessing the valuation of a country's entire stock market. It is calculated by dividing the total market capitalization of all listed companies by the country's gross domestic product (GDP). A value above 100 percent indicates a possible overvaluation, while values below 75 percent can indicate a potential undervaluation.

The world-famous investor Warren Buffett himself described this indicator as “probably the best single measure of where valuations are at any given time”. The indicator is used to assess market trends and identify potential over- or undervaluations of the market as a whole.
