The main U.S. stock indexes hit record intraday highs on Monday, led by financials and industrials, as the so-called "Trump trade" sparked back to life on renewed optimism about the economy.
The three main indexes closed at record highs on Thursday and Friday rose after President Donald Trump vowed to make a major tax announcement in the next few weeks.
The S&P 500 .SPX has surged 8.3 percent since Trump's Nov. 8 election through Friday's close, fueled by expectations he will lower corporate taxes, reduce regulations and increase infrastructure spending.
While the rally had stalled amid concerns over Trump's protectionist stance and lack of clarity on policy reforms, the S&P 500 has not dropped more than 1 percent in 84 trading days, indicating investors were giving Trump the benefit of doubt.
Investors were also comforted by the two-day U.S.-Japan summit held over the weekend apparently having ended smoothly without Trump talking tough on trade, currency and security issues.
The Japanese yen, the demand for which rises when risk appetite falls, was the biggest underperformer among major currencies. World stocks rose, with Asian shares rallying to a 1-1/2-year high.
Global markets are following the leader (U.S. stocks) after the resurgence of the "Trump trade", Peter Cardillo, chief market economist at First Standard Financial wrote in a note.
