Wall Street ended higher on Monday, extending Friday's gains, as expectations grew for a second term for Donald Trump after a failed assassination attempt raised hopes for looser regulation.

Expectations that the Federal Reserve could cut its key interest rate as early as September also helped boost risk appetite among investors.

While all three major U.S. stock indexes closed well below their intraday highs, the Dow Jones Industrial Average hit a record close.

Small, economically sensitive stocks (.RUT) and transportation stocks (.DJT) have outperformed the broader market.

The assassination attempt on Trump, the presumptive Republican presidential nominee, on Saturday in Pennsylvania appears to have boosted his chances of being elected.

A Trump presidency is expected to usher in more aggressive trade policies, further tax cuts, and deregulation in areas ranging from climate change to cryptocurrencies.

"The main event — the assassination attempt on Donald Trump — hasn't quite hit its mark," said Sam Stovall, chief investment strategist at CFRA Research in New York. "GDP forecasts are unchanged, expectations for a Fed rate cut in September are unchanged, and corporate earnings are ahead of expectations."

"So the market momentum remains driven by investor optimism," Stovall added.

Investor sentiment was also supported by expectations that the Federal Reserve will begin a rate-cutting cycle as early as September, with as many as three cuts possible before the end of the year.

"A rate cut in September is virtually guaranteed," said Ross Mayfield, an analyst at Baird Investment Strategy in Louisville, Kentucky. "We're in the same position we were seven months ago, which is the promise of a Fed rate cut without the risk of a recession. But there's still a lot riding on the Fed's actions."

Speaking to the Economic Club of Washington, Fed Chairman Jerome Powell reiterated his confidence that the U.S. economy can avoid a recession, with recent data showing progress in bringing inflation back to the central bank's 2% target.

Other stocks that would likely benefit from a possible second Trump term also saw gains, with gun maker Smith & Wesson (SWBI.O) and correctional facility operator GEO Group (GEO.N) up 11.4% and 9.3%, respectively.

Long-term U.S. bond yields rose on speculation that Trump's policies will lead to higher government debt and inflation. Meanwhile, cryptocurrency stocks rose along with Bitcoin as Trump casts himself as a cryptocurrency advocate.
