Odaily reported that The Kobeissi Letter published a data analysis on X showing that the semiconductor sector’s weight in the U.S. equity market has continued to rise. According to the post, semiconductors now represent about 18.8% of the total market capitalization of the S&P 500, marking a new historical high for the sector’s share within the index.
The analysis said this figure has increased by more than three times since 2022. Over the same period, the semiconductor index SOX has gained about 546%, indicating that the industry has held a clear leading position during the current technology cycle. As the sector’s market-value share has expanded, its influence on the broader S&P 500 has also increased.
In a historical comparison, the current semiconductor weight in the S&P 500 has already exceeded more than half of the peak level seen during the 2000 internet bubble period. The Kobeissi Letter stated that U.S. equity markets are continuing to concentrate around AI and the semiconductor supply chain, while technology stocks’ impact on the overall index has reached an extreme level by historical standards.
