Cameron Dawson highlights that semiconductor stocks now make up 18% of the S&P 500, more than double their weight during the tech bubble peak, driven mainly by giants like NVIDIA. This concentration extends to value and emerging market indexes, with companies like Google, Micron, SK Hynix, Samsung, and TSMC holding large shares. Even mid-cap stocks like SanDisk and AMD have seen massive gains, reflecting the dominance of AI and data center demand. Dawson warns that traditional diversification strategies from the dot-com era may fail now, as many indexes are heavily correlated due to the AI-driven semiconductor boom, making true diversification harder for investors.
