The S&P 500’s Concentration Offers a Lesson on Diversification
The odds are high that you have read or heard about artificial intelligence or Chat GPT this year. In the stock market, there is a small group of stocks known as the “7 Tech Titans”, which includes leading technology firms exposed to the AI theme. The group of stocks has significantly outperformed this year due to growing excitement about AI, which has in turn increased its weight in the S&P 500. The five largest companies in the S&P 500, which are all part of the 7 Tech Titans, account for 22% of the entire index’s total market capitalization. These five companies include Apple, Microsoft, Amazon, NVIDIA, and Alphabet (the parent company of Google).
