NEW YORK (AP) — Financial giant Citigroup reported a 7 percent rise in fourth quarter profits on Wednesday, helped by a strong performance in the bank's trading business, a theme that has repeated itself with all the major Wall Street banks this quarter. Citi's institutional clients group, which includes the firm's investment bank and trading, reported net income of $2.47 billion in the quarter compared with $1.26 billion in the same period a year earlier. Citi's global consumer banking business, which includes its retail bank and credit card business, had net income of $1.27 billion, down 7 percent from a year earlier.
