Shares of Facebook rose, last up 3.1 per cent, after Credit Suisse upgraded the stock to "outperform".
Solid quarterly earnings helped lift shares of companies including Netflix, Comcast, United Technologies and Travelers, respectively up 5.9 per cent, 2.3 per cent, 1 per cent, and 0.4 per cent.
To be sure, it wasn't all good news. Shares of McDonald's slipped 0.2 per cent after the company posted another quarterly decline in sales.
On the housing front, a National Association of Realtors report showed that existing home sales fell 0.2 per cent to an annual rate of 4.59 million units, the lowest level since July 2012. It was still better than economists had anticipated and provided reason for optimism that the housing market is stabilising.
"The negative housing momentum, which was exacerbated by severe weather conditions during the winter months, may be starting to fade," Gennadiy Goldberg, an economist at TD Securities in New York, told Reuters.
Meanwhile, demand for a US Treasury auction of US$32 billion of two-year notes drew lacklustre demand in a sign that the Federal Reserve has not managed to alleviate concerns it might lift borrowing costs sooner than anticipated.
"A weak auction shows the market has lost some confidence in the Fed's ability to clearly articulate its message," Thomas Simons, a government-debt economist in New York at Jefferies, one of the primary dealers that are required to bid at the auctions, told Bloomberg News before the sale. "When the Fed will ultimately raise rates remains a big question."
In Europe, the Stoxx 600 Index ended the day with a 1.4 per cent increase from the previous close. The UK's FTSE 100 gained 0.9 per cent, while France's CAC 40 rose 1.2 per cent, and Germany's DAX rallied 2 per cent.
