Fourth quarter revenue at financial giant Goldman Sachs is disappointing investors as the company pursues a strategy that so far isn’t panning out.

The firm reported that its trading desks that once the most profitable companies in the industry showed a sharper decline in revenue that their competitors, according to a New York Times report.

As a result, revenue in the final quarter of 2014 dipped 12 percent from last year, and profit declined 7 percent to $2.17 billion, which came out to about $4.38 per share, compared to $2.33 billion in profits in 2013 and $4.60 per share.

Goldman’s profit had risen for all of 2014, and the results from the last quarter actually outperformed analysts expectations, but the quarterly results only emphasized concerns about Goldman’s business model.

The results caused the bank’s stock to decrease 0.7 percent on Friday compared to the broader market, which rose 1 percent. For the week, Goldman endured a 5 percent drop.

Chief Financial Officer Harry Schwartz said that while the results were disappointing, the stock trading desks were performing better in the fourth quarter, according to the Times report. However, he noted that the company could do better.

Traders who sell bonds, currencies, and commodities had been Goldman’s biggest moneymaker in recent years, but with interest rates staying low, that practice has been challenging. To deal with this issue, Goldman’s competitors have been avoiding fixed-income trading, something that Goldman said it plans to stick with and hopes to capitalize on as competitors flee the arena. The latest quarter’s results suggest that that strategy has not yet panned out for the firm.

Goldman’s problems have been compounded by a bad loan to a Portuguese bank earlier this year, with the Portuguese central bank making a ruling that would make it unlikely that the $835 million loan to be repaid.

However, Goldman posted strong gains in other areas, especially in consulting with companies on mergers and acquisitions. Fees from that work jumped 18 percent from a year prior. Also, the firm is trying to expand its business in managing the assets of major investors, which is bringing in more revenue.
