Paul Tudor Jones warns of negative 10-year returns amid soaring US market valuations
Speaking on the Invest Like the Best podcast, Tudor Investment's founder argues that a shift from net buybacks to new IPO supply and extreme capitalisation ratios pose structural risks for long-term holders

Legendary investor Paul Tudor Jones has cautioned that current valuations in the United States stock market could result in negative returns for investors over the next decade. The macro hedge fund manager, who is widely known for profiting an estimated $100 million from the 1987 market crash, made the assessment while appearing on the Invest Like the Best podcast.
Jones highlighted that the S&P 500 price-to-earnings ratio currently stands at 22. He noted that historically, a ratio at this level implies a loss of capital for investors holding positions for ten years. While he emphasised that there is no imminent crash, he described the market as "over-equitised," a state where total market capitalisation has reached 252 per cent of gross domestic product. This figure, he stated, is the highest level seen since the 1929 crash.
The structural risks identified by Jones include a significant shift in market dynamics. For the past decade, US companies have been net buyers of their own stock through buybacks, which reduced supply and supported prices. However, he pointed to a changing trend where major initial public offerings, such as those from SpaceX and OpenAI, are introducing new supply into the market. This shift from net buying to net selling could increase market saturation and make it difficult for investors to generate gains.
Jones also outlined the broader economic consequences of a potential correction in such a highly leveraged market. He estimated that a 35 per cent plunge in stock valuations would wipe out wealth equivalent to 80 to 90 per cent of one full year of US economic output. Such an event could trigger a bond market crisis and cause federal budget deficits to balloon, as capital gains tax revenue would drop to near zero.
In response to these risks, Jones has adjusted his own portfolio to prioritise diversification. He recently increased his hedge fund's exposure to the SPDR Gold ETF by 49 per cent while lowering positions in technology giants like Apple and Alphabet. He suggested that investors consider hedging strategies involving international markets, gold, Bitcoin, and real estate to protect against the potential volatility in US equities.
