S&P 500 Nears Four-Year Bull Market Milestone Amid AI-Driven Gains and Rising Rate Risks

Key points

• The S&P 500 is near record highs, marking four years since the October 2022 market low.
• AI spending and corporate profit growth, expected to rise over 35% this year, are the primary drivers of the rally.
• Nvidia’s market capitalization has surged to $5.8 trillion, making it the world’s largest company by value.
• The 10-year Treasury yield has reached approximately 5.2%, its highest level in 24 years.
• The top 10 companies in the S&P 500 now account for about 40% of the index's total value.

Background

Recent archive entries highlight the broader impact of this bull market, including a record number of 401(k) millionaires and increased early retirements among older workers. However, warnings have also emerged, such as Ray Dalio’s recent caution that AI debt-fueled spending could lead to a market correction if interest rates continue to rise.

How outlets are covering it

While Carson Group’s Ryan Detrick remains bullish, noting that historical data suggests strong second quarters often precede robust fourth quarters, other analysts express caution. Edward Jones’ Angelo Kourkafas acknowledges the market’s fundamental strength but advises reducing risk due to concentration and rising bond yields. Ameriprise’s Anthony Saglimbene warns that the 'easy money' phase of AI is over, and tech companies must now prove that current spending translates into future profits. The New York Post and Reuters emphasize the looming risks from Federal Reserve rate hikes and spiking Treasury yields, which could sap equity momentum.

Why it matters

The sustainability of this bull market depends on whether AI investments can deliver tangible returns. If the Federal Reserve continues to hike rates to combat inflation, or if AI spending fails to translate into profits, the market could face a sharp correction. Investors are increasingly watching for signs of weakness in the tech sector, which dominates the S&P 500's performance.

What to watch

Markets will likely remain volatile leading up to the US midterm elections in November. Investors will closely monitor Federal Reserve policy decisions, Treasury yield movements, and corporate earnings reports to assess whether AI spending can sustain the current rally or if a correction is imminent.
