Goldman Sachs earned its biggest quarterly profit in more than three years, beating Wall Street expectations, as its investment bankers brought in more fees from deals and debt sales, while its traders benefited from a surge in market activity.

Goldman Sachs said its profit more than doubled in the fourth quarter, boosted by companies’ growing appetite for dealmaking. Profit jumped 105% to $4.11 billion. That amounted to $11.95 per share, which was far better than the $8.
