US stock markets closed sharply higher on Monday, with the Dow Jones Industrial Average reaching a new all-time high.
Broad buying interest drove the three major indices into positive territory, capping a session defined by renewed investor confidence.
The rally followed a highly visible ceremonial opening of the trading week.
President Donald Trump rang the opening bells for the New York Stock Exchange and Nasdaq from the Oval Office, predicting that the market was "going to go through the roof." The symbolic gesture coincided with a strong start to the week, as investors pushed major benchmarks higher in the first minutes of trading.
The Dow Jones Industrial Average led the advance, climbing to a new milestone level early in the session and holding those gains through the close.
The broader market participation suggests that the buying interest was not limited to a single sector, but reflected a general risk-on posture among US investors.
