The US stock market has delivered remarkable performance in 2023-24, reminiscent of the late 1990s dot-com era, with the S&P 500 posting gains of nearly 27% in 2024 following a 24.2% increase in 2023.

Market momentum and key drivers: Artificial Intelligence has emerged as the primary catalyst for market gains, replacing the dot-com stocks that drove the late 1990s rally.

  • Nvidia’s stock value has more than doubled in 2024, following a threefold increase in 2023, driven by strong demand for its AI chips
  • Super Micro Computer, a server manufacturer for AI applications, has surged nearly 48% in 2024 after tripling in value the previous year
  • The S&P 500 has set 50 record highs in 2024, demonstrating sustained market strength

Economic context: Despite earlier concerns about a potential recession, the economy has shown resilience in the face of the Federal Reserve‘s aggressive interest rate hikes.

  • The economy has successfully navigated through the post-COVID recovery period
  • The Federal Reserve’s interest rate increases to combat inflation have not triggered the widely feared recession
  • Market optimism has been bolstered by expectations of future interest rate cuts

Historical perspective: The current market trajectory shares notable similarities with the late 1990s bull run, though with different underlying drivers.

  • Following similar strong performances in 1998-99, the market continued its ascent in 1999 with a 19.5% gain
  • The dot-com bubble eventually burst in early 2000, leading to a multi-year market decline
  • The 2001 recession marked the end of that era’s bull market

Expert outlook and cautionary signals: Market strategists offer mixed perspectives on the sustainability of current market gains.

  • UBS Global Wealth Management forecasts a more modest 9% gain for the S&P 500 in 2025, targeting 6,600
  • Critics point to elevated valuations as stock prices have outpaced corporate profit growth
  • The absence of a 10% market correction in 2024, which typically occurs every few years, raises concerns about potential market vulnerability

Risk assessment: The current market enthusiasm may be overlooking potential challenges ahead, warranting a more measured approach to investing.

  • Market strategist Anthony Saglimbene suggests excessive optimism may be clouding investors’ judgment about potential risks
  • The parallels with the dot-com era serve as a reminder that periods of exceptional returns can be followed by significant market corrections
  • Current valuations and investor sentiment suggest a need for increased caution in the near term

The big picture: The DOE's roadmap aims to "deliver the public infrastructure that supports the fusion private sector scale up in the 2030s," but acknowledges it cannot commit to specific funding levels and remains subject to Congressional appropriations.
