Wall Street bank Morgan Stanley's profit doubled in the last quarter of the year, far exceeding expectations, as trading activity surged following the U.S. presidential election.
Earnings applicable to common shareholders soared to $1.51 billion in the fourth quarter from $753 million a year earlier, while earnings per share increased to 81 cents from 39 cents, the bank said on Tuesday.
Analysts on average had expected a profit of 65 cents per share, according to Thomson Reuters I/B/E/S.
Bank stocks have rallied since the election, on the hope that the new Trump administration will usher in a new era of looser bank regulations along with economic growth.
Morgan Stanley Chief Financial Officer Jonathan Pruzan, however, raised questions about how long this investor enthusiasm will last.
"There is clearly optimism out there, but how long that holds is really a question, given that political and geopolitical events can change sentiment very quickly," Pruzan said in an interview.
Trading in debt securities and stocks shot up in the wake of Donald Trump's surprise election victory on Nov. 8 as investors took the view that he would push policies that would boost the U.S. economy and kindle inflation.
Revenue in the bank's fixed-income business jumped to $1.5 billion in the quarter from $550 million in the same period last year.
JPMorgan Chase & Co, the No. 1 U.S. bank by assets, had reported a 31-percent rise fixed-income revenue last week, while second-ranked Bank of America Corp said its revenue from trading fixed-income securities, currencies and commodities rose 12 percent.
Citigroup Inc and Goldman Sachs Group Inc, Morgan Stanley's chief rival, report on Wednesday.
Morgan Stanley's shares were up 1.4 percent at $44.40 in premarket trading, having risen 28.5 percent since the election through Friday's close.
Revenue from equities trading, a business in which Morgan Stanley is typically strong, rose to $2 billion from $1.8 billion.
Revenue from wealth management rose 6.4 percent to $3.99 billion. The pretax margin in the business increased to 22 percent from 20 percent a year earlier.
Total revenue jumped 16.6 percent to $9.02 billion, beating the average estimate $8.47 billion.
The bank's return on equity was 8.7 percent in the quarter, short of Chief Executive James Gorman's target of 9 percent to 11 percent by the end of 2017.
Investment banking revenue, which includes income from advising on mergers and acquisitions as well as underwriting bond and share offerings, rose 5.1 percent to $1.38 billion.
The bank, which has said it wants to cut costs by $1 billion this year, said non-interest expenses rose 7.6 percent to $6.78 billion in the latest quarter. Total compensation and benefits expenses rose 11.9 percent to $4.08 billion.
Morgan Stanley ranked second in worldwide announced M&A deals during 2016, according to Thomson Reuters data.
The bank laid off a number of senior investment bankers earlier this month and cut bonuses by roughly 15 percent, according to sources familiar with the matter.
