US stock market hits record valuation

The US stock market has reached its most expensive valuation in history, with the Warren Buffett Indicator—the ratio of total market capitalization to GDP—jumping to 227%. This level surpasses previous peaks seen during the Dot Com Bubble and the Global Financial Crisis, signaling extreme market valuations. The surge continues a historic three-week rally that has been the fastest in nearly 45 years, driven by massive investor inflows into key sectors like semiconductors.
