Meanwhile, Fed Vice Chair Stanley Fischer warned that any increase in interest rates will be gradual.
"Liftoff says we're going straight up with the interest rate," Fischer said during a question-and-answer session after a speech on financial crises, Bloomberg reported. "Well, we're going up with the interest rate, then along, and then another little jump. That's not liftoff, that's crawling."
Gains in shares of Microsoft and those of Wal-mart, recently trading 1.6 percent and 0.9 percent higher respectively, led the Dow higher.
Shares of Microsoft rose after the Wall Street Journal reported the company has agreed to acquire 6Wunderkinder, a Berlin-based startup behind the Wunderlist to-do list app, for between US$100 million and US$200 million.
Shares of Intel declined, last 1.7 percent weaker for the Dow's biggest decliner, after it agreed to buy Altera for US$16.7 billion.
"Management teams are looking at their business and predicting little growth going forward," Gus Richard, an analyst at Northland Securities, told Bloomberg. "The M&A wave is a function of them trying to drive earnings growth. Intel's purchase of Altera is one of the few strategic moves that is being made currently."
