Goldman Sachs reported Thursday that its fourth-quarter profit fell 21 percent as revenue from mortgages and trading in bonds and other securities weakened.

The Wall Street bank earned $2.25 billion in the October-December quarter after paying dividends on preferred shares, down from $2.83 billion in the same period a year earlier.

That worked out to $4.60 per share, down from $5.60 per share a year earlier. The results were well above the earnings of $4.18 per share analysts were expecting.

Revenue slipped 5 percent, to $8.78 billion, but exceeded analysts’ forecast of $7.72 billion.

It was the first year-on-year decline in earnings at Goldman Sachs since the second quarter of 2012, when income fell 12 percent to $927 million.

Shares fell $3.58, or 2 percent, to close at $175.17.
