The Kobeissi Letter(@KobeissiLetter):Big Tech’s dominance is unprecedented: The Technology, Media, and Telecom (TMT) sector now accounts for a record 49% of the S&P 500’s market value. This is ~9 percentage points above the 2000 Dot-Com Bubble peak and ~20 percentage points above the late-1960s high. The tech sector now carries a larger weight than the financials, cyclicals, and defensives sectors combined. By comparison, TMT accounted for just ~19% of the S&P 500 during the 2008 Financial Crisis. The US stock market has never been this reliant on tech.
