Citigroup traders had their best third-quarter results in at least 10 years, benefiting from increased volatility across asset classes in recent months. The Wall Street giant's marketing division's third-quarter revenue rose 1% to $4.82 billion, a surprising increase. Just a few weeks ago, the company also warned investors that it expected market revenue to decline. Stock trading revenue surged 32%, driving the business forward. Although the surge in credit card non-performing loans dragged down profits during the quarter, the revenue of Citi's four other major businesses also increased compared to the same period last year.
