The Buffett Indicator & Stock Market Valuation

Weekly Investment Update | By Brian Schreiner

The Buffett Indicator was popularized by Warren Buffett in the early 2000s when he described it as "probably the best single measure of where valuations stand at any given moment." It has been widely used to assess whether the stock market is overvalued or undervalued relative to the economy.

The Buffett Indicator is a valuation metric that compares the total market capitalization of a country's stock market to its Gross Domestic Product (GDP).

Here’s the formula:

Buffet Indicator = (Total Stock Market Capitalization / GDP) x 100

When the indicator is below 75%, stocks are considered undervalued; between 75% and 100%, fairly valued; between 100% and 120%, slightly overvalued; above 120%, overvalued; and above 200%, extremely overvalued.

As of today, the Buffett Indicator stands at 204%, well above historical norms, indicating that the stock market is highly overvalued relative to the economy.

WHAT DOES THIS MEAN FOR INVESTORS?

During periods when market valuations are extremely high, legendary investors such as Howard Marks, Stan Dunkenmiller and Ray Dalio advocate a risk-conscious and defensive approach.  

Instead of making drastic all-in or all-out moves, investors should consider gradually shifting to a more conservative stance as stocks become increasingly over-valued.

Specifically, be more defensive and reduce aggressive risk-taking and avoid speculative investments such as high-growth stocks overhyped assets. 

Reduce leverage to protect against market downturns. Focus on capital preservation rather than chasing high returns.  Stick to investments with solid fundamentals and avoid "story stocks" driven by hype. 

When stock market valuations are high, it’s wise to increase liquidity and “dry powder” by increasing cash or cash-equivalents so that you’re ready to take advantage of market corrections.

Consider increasing allocations to alternative investments and defensive assets such as private credit, infrastructure and defensive assets such as gold and real estate.

We can’t predict exactly when markets will turn, but we can use technical indicators, charts and active trading strategies that seek to reduce risk.  And we should focus on probabilistic thinking (which recognizes uncertainty and multiple possible outcomes) rather than deterministic thinking (which assumes certainty and single or fixed outcomes). 

It also helps to understand and assess market psychology by evaluating investor sentiment.  When optimism is excessive and valuations are stretched, wise investors are right to be skeptical.  

In summary, when valuations are high, we believe that investors should be defensive, selective, and liquid while preparing for future opportunities rather than chasing returns. We are focused on managing risk rather than chasing returns and trying to predict the next downturn.  α
