MAG-7 Ends Bull Market By Reducing Buybacks

Phoenix Capital Research strategist Graham Summers argues that the 2022 bull market, accelerated by AI after OpenAI’s ChatGPT launch on November 30, 2023, was driven primarily by MAG-7 companies. He cites MAG-7 accounting for 75% of S&P gains, 80% of corporate profits, and massive capex that led to $121 billion of 2025 bond issuances, reducing buybacks and increasing market vulnerability.
