The top ten US technology stocks now represent nearly 40% of the S&P 500's market capitalization, the highest concentration since the late 1990s dotcom bubble. This surge is driven by giants like Microsoft, Apple, NVIDIA, Amazon, Alphabet, and Meta, with NVIDIA surpassing a $5 trillion market cap. UBS warns that such concentration echoes past market bubbles and corrections, recommending investors rebalance portfolios by diversifying beyond mega-cap tech stocks into other sectors and lesser-known companies. This approach aims to mitigate risks associated with extreme tech stock concentration while still benefiting from growth areas like AI infrastructure and industrial adoption.
