Goldman Sachs has underscored the twin trends of surging advisory revenues and plunging equity capital markets income that have dictated the health of Wall Street banks' third-quarter investment banking performance, with its results outstripping its US rivals on both fronts.

The US bank, which on October 15 published its results for the three months to September 30, reported that its revenues from equity underwriting plunged 55% from their year-before level to just $190 million.
