AI and the S&P 500

Artificial intelligence (AI) continues to impact markets like the S&P 500 in 2024. If you are already invested in broad-based ETFs, you may be invested in AI, whether you realize it or not. In this post, we discuss how AI companies are influencing cap-weighted indices.

Fear of Missing Out

Jason Zweig at The Wall Street Journal recently wrote an article about one of the leading AI companies Nvidia. In his article, he noted how this company was now more than 4% of the S&P 500 index, thanks to its recent rise in share price.

And, other companies working in the AI space are also seeing very positive share price increases, like Microsoft. In fact, according to this page on ETF.com, Microsoft and Nvidia now account for about 11.5% of the S&P 500 index. This weighting of AI in the S&P 500 is due to the S&P 500 being a “cap-weighted” index.

So, even if an investor thinks they may have “missed out”, they have not if they owned an S&P 500 ETF or some other cap-weighted index fund.

Other firms in the S&P 500

Because the S&P 500 is cap-weighted, the firms in this index become more (or less) significant as their market capitalization increases (or decreases). The image below shows the current top-10 holdings in the S&P 500 ETF (ticker: IVV). Note that over half of those in this list are tech firms that are at the forefront of AI. In fact, for investors in Apple, there may not be enough investment in AI.

ETF investor options to embrace or avoid AI

Hopefully, ETF investors realize that they may already have AI investments, if they are invested in one of the ETFs tracking the S&P 500, like VOO, IVV, or the oldest ETF SPY. Alternatively, ETF investors wishing to embrace AI more may seek tech-centric ETFs, like XLK. Or, by seeking dividend-paying stocks not seeking growth from AI, an ETF investor may seek funds like DVY or VTV. Investor preference for growth in the AI space will likely affect investments for many years to come.
