What happens when 40% of the S&P 500 is held up by just five companies? Now add valuations that demand absolute perfection. Nothing breaks as long as those companies keep outperforming the rest of the world. But they are not. China is already advancing faster across several of the most important AI sectors. That means the expectations holding up America’s largest companies are beginning to fail. And when market leadership becomes this narrow, the collapse does not begin with panic. It begins quietly. A missed expectation. A loss of dominance. A slow shift in capital. Then suddenly, everyone realizes the foundation is gone. This may become one of the most violent market crashes in history. And it has already started. Most people just have not noticed yet. Stay safe.
