What's going on?
U.S. stocks have risen to record highs, driven largely by a handful of big tech companies, with Nvidia leading the way.
What does this mean?
Big technology companies are driving the market, with NVIDIA up 147% this year to become the world's second-largest company and account for about one-third of the S&P 500's gains. NVIDIA, along with other big names like Microsoft, Meta Platforms, Alphabet and Amazon.com, have driven 60% of the S&P 500's 12% total return so far this year. By the end of May, the combined weight of Microsoft, Apple, NVIDIA and Alphabet in the S&P 500 reached nearly 24%, the highest in 60 years. These impressive gains are exciting, but they also raise concerns about a potential market downturn.

Why should you care?
For markets: Ride the technology wave.
The market's current narrow focus is evident from the equal-weighted S&P 500's slight gain of just 4.5% compared to a 12% rise in traditional indexes. Financial, energy and industrial sectors performed well in the first quarter of 2024 but lagged in the second quarter, driven primarily by enthusiasm for AI and strong first quarter earnings from mega-cap technology companies. However, recent data suggests an economic slowdown, reflecting potential market risks, including a weak US manufacturing report.
Overall picture: Balance on the technical scale.
Some analysts believe the market could expand as other stocks in the S&P 500 see improving earnings, but there are risks. If Nvidia's stock faces a correction, it could have a knock-on effect on the broader market. Experts such as Jones Trading's chief market strategist have warned of these potential risks, while others at Chase Investment Counsel believe concentration is a sign of economic strength. Ultimately, broader gains are considered preferable for long-term market health, highlighting the need for a diversified approach.
