Even so, Wall Street was mixed. In 3.16pm trading in New York, the Dow Jones Industrial Average rose 0.2 per cent. However, the Nasdaq Composite Index inched 0.04 per cent lower. In 3.02pm trading, the Standard & Poor's 500 Index was little changed from the previous day's close.
Earlier in the day, the Dow climbed to a record 22,036.10.
Some investors are concerned the gains might not last.
"The market gain has been built on a narrow group of issues. That typically is not indicative of great health," Mark Luschini, chief investment strategist at Janney Montgomery Scott in Philadelphia, told Reuters.
"I would not be shocked ... if we saw a pullback."
Gains in shares of Apple and those of McDonald's, recently up 5.4 per cent and 1.2 per cent respectively, led the Dow higher. Keeping a lid on the advance were declines in shares of Walt Disney and those of Verizon, recently down 2.1 per cent and 1.8 per cent respectively.
Restaurant Brands International posted quarterly profit that exceeded expectations, bolstered by its Burger King brand, though sales at Tim Hortons and Popeyes fell short of the mark.
Comparable sales at Burger King rose 3.9 per cent, while those at Tim Hortons slipped 0.8 per cent and those at Popeyes fell 2.7 per cent.
"We had notable strength at Burger King with both strong comparable sales growth and net restaurant growth," Daniel Schwartz, chief executive officer, said in a statement. "We also made good progress integrating Popeyes and continue to be excited about the long term growth potential for the brand."
The stock traded 0.1 percent higher at US$59.30 as of 2.07pm in New York, after rising as high as US$60.78 and falling as low as US$57.95 earlier in the day.
Meanwhile, the latest US jobs data offered fresh signs of strength. An ADP Research Institute report showed US private employers added 178,000 jobs last month, following an upwardly-revised increase of 191,000 jobs in June.
"The American job machine continues to operate in high gear," Mark Zandi, chief economist at Moody's Analytics in West Chester, Pennsylvania, said in a statement, Bloomberg reported. Moody's produces the figures with ADP.
"Job gains are broad-based across industries and company sizes, with only manufacturers reducing their payrolls," Zandi noted. "At this pace of job growth, unemployment will continue to quickly decline."
Attention now turns to the government's nonfarm payrolls data, scheduled for release on Friday, which is expected to show that US employers added about 180,000 workers in July.
In Europe, the Stoxx 600 Index finished the session with a decline of 0.4 per cent from the previous close. The UK's FTSE 100 Index fell 0.2 per cent, while France's CAC 40 Index shed 0.4 per cent, and Germany's DAX Index dropped 0.6 per cent.
