Summary
- Tech sector now makes up over a third of the S&P 500's total market cap, matching a record high from the dotcom bubble era
- The tech sector's market cap of $18.5 trillion is larger than the entire market cap of every country outside the U.S.
- Upcoming earnings reports from major tech giants like Alphabet, Microsoft, Apple, Amazon, and Meta Platforms will be crucial for the S&P 500's continued rally

The technology sector's dominance in the stock market has reached levels not seen since the dotcom bubble era, raising concerns about the broader market's vulnerability. According to Goldman Sachs' trading desk, the S&P 500 tech sector now makes up more than a third of the index's total market capitalization, matching a record high from the late 1990s and early 2000s.
The tech sector's market cap has swelled to a staggering $18.5 trillion, which is larger than the entire market cap of every country outside the United States. This outsized influence means the broader market is increasingly susceptible to idiosyncratic pressures and performance within the tech space.
In the coming weeks, the market will be closely watching the earnings reports from major tech giants like Alphabet, Microsoft, Apple, Amazon, and Meta Platforms. Strong numbers from these companies will be crucial for the S&P 500 to continue its march to record levels. However, if the rest of the S&P 500 outside of tech shows signs of fatigue, it could spell trouble ahead for investors.
