Wall Street tore through the gloom on Monday, with the Dow Jones Industrial Average — the 130-year-old index tracking 30 of America's biggest companies — closing above 52,000 for the first time ever, while the Nasdaq, home to most of the world's big tech and AI names, jumped 2%. Today's Daily Business Index, our daily 0-to-100 reading of global business health where 50 is neutral, comes in at 52.5, a solid three-point jump from yesterday's 49.5. The catalyst wasn't a single earnings report — it was relief. A Supreme Court ruling protected the independence of a Federal Reserve governor, oil kept sliding off its war-era highs, and the panic that gripped chip stocks last week finally found a floor.
