Shares of Citigroup climbed, last up 4 percent, after the bank posted earnings that surpassed estimates.
"The quarter had more than its fair share of volatility and our results speak to the resilience of our franchise globally," Citigroup Chief Executive Michael Corbat said in a statement. "And despite revenue headwinds, we once again proved our ability to manage our risk, our expenses and our capital. We remain on track to deliver our full-year efficiency and ROA targets."
Meanwhile, Goldman Sachs posted a quarterly profit that fell short of analysts' expectations.
"We experienced lower levels of activity and declining asset prices during the quarter, reflecting renewed concerns about global economic growth," Goldman Sachs Chief Executive Officer Lloyd Blankfein said in a statement. "We continue to see strong levels of activity in Investment Banking and growth in Investment Management."
Shares of Goldman Sachs initially dropped as low as US$175.76, but recovered later in the session to trade 2.4 percent stronger at US$183.81.
"Unless such a market rout happens again, I would expect fourth-quarter trading revenues at the banks to improve compared to third-quarter," Erik Oja, an analyst at S&P Capital IQ, told Reuters.
Shares of Wal-Mart continued the previous day's slide, last 2.1 percent weaker, on a forecast drop in earning per share for its fiscal 2017 year.
On the economic front, the latest data offered further reasons for the US Federal Reserve to keep interest rates on hold. A Labor Department report showed initial unemployment claims fell by 7,000 to 255,000 in the week ended October 10. A separate Labor Department showed the consumer price index slid 0.2 percent in September, following a 0.1 percent decline in August.
"The bad news is that the US economy seems to be having a bit of a wobble, the good news is that it means the Fed was right not to raise rates in September," Ben Kumar, an investment manager at Seven Investment Management in London, told Bloomberg. "People are giving a bit of credibility back to Janet Yellen, that means people are a little bit more languid about the rate rise speculation."
In Europe, the Stoxx 600 Index ended the day with a 1.5 percent rally from the previous close. The UK's FTSE 100 Index rose 1.1 percent, while France's CAC 40 Index increased 1.4 percent, and Germany's DAX Index advanced 1.5 percent.
