Mega-IPOs Could Push Tech Weighting Past Bubble Levels, Visa Debut Cited
V•Bank of America strategist Michael Hartnett warns that planned SpaceX and OpenAI IPOs could push technology weighting beyond previous market bubbles, with tech already representing over 44% of the S&P 500. He noted past “toppy” offerings like Visa’s IPO were followed by nine- to twelve-month market declines.
1. Hartnett's Warning on Mega-IPOs
Bank of America strategist Michael Hartnett warns mega IPOs eyed by SpaceX and OpenAI risk pushing tech concentration beyond levels seen in the Roaring ’20s and other historic bubbles.
2. Technology's Growing S&P Weighting
Technology already accounts for over 44% of the S&P 500 Index, intensifying tracking challenges for funds limited by risk management constraints.
3. Past 'Toppy' Offerings Cited
Hartnett highlighted that debuts like Visa’s IPO and AIA Group previously proved inconsequential, with markets trading lower nine to twelve months after their “toppy” offerings.
4. Implications for Asset Allocators
Elevated tech concentration may compel allocators to cut exposure to major tech names, potentially concealing weaknesses in consumer and financial sectors.
