On May 11, statistics showed that from May 2024 to June 2026, the S&P 500 index has increased by 142%. However, if AI stocks are excluded, this figure drops sharply to 16%. AI stocks currently account for 45% of the total market value of the S&P 500 index, marking a historic high for a single thematic sector within the index. Capital Economics predicts that the S&P 500 index will reach 7250 by the end of the year. Achieving this target would mean the market will have the highest concentration of index composition in history. Additionally, the $1.4 trillion debt associated with AI warrants caution, encompassing various forms from corporate bonds issued by mega-cap companies to leveraged positions in AI-related stocks. If market credit conditions tighten in the future, or if any major AI company reports disappointing revenue growth, the $1.4 trillion in AI-related borrowing could quickly evaporate. (Cryptobriefing)
