The year is coming to a close, so it's a great time to take a look back at the companies you own and how they fared in 2011.

There's no sugar-coating it: It's been a trying year to own Goldman Sachs (NYSE: GS) stock. Year to date, Goldman's stock has fallen 44% even though the S&P 500 has managed a slight gain for the year. Of course, a stock's performance doesn't always mirror the company's performance. So let's take a closer look at Goldman's 2011.

What went down in 2011
It was tough for any company to escape the economic woes of 2011 -- whether we're talking about the sputtering recovery in the United States or the abysmal hole that the European Union has ended up in thanks to heavily indebted member countries. For investment banks, those economic factors meant that companies were less interested in raising new capital through debt and equity issuance.

That said, competitively Goldman didn't stack up well through the first nine months of the year. Its total investment banking fees fell 11%, more than the overall industry and far more than competitors such as JPMorgan Chase (NYSE: JPM), Morgan Stanley (NYSE: MS), and Citigroup (NYSE: C), which saw fees fall 3%, 1%, and 4%, respectively. Bank of America (NYSE: BAC), however, saw its fees for the year rise by 3%.

Maybe even more concerning was the bank's performance in merger and acquisition advising in particular, which is a key strength for Goldman's advisory business. Though Goldman continued to top the industry in M&A fees, its fees there fell 7% versus a 2% average increase for the top banks. No. 2 M&A advisor Morgan Stanley saw its fees leap 17%, while JPMorgan's and B of A's fees climbed a respective 10% and 32%.

Of course, the advisory business for Goldman has become less of a focus in recent years as the company has raked significantly more through trading activities and principal investments. For 2010, for instance, 75% of Goldman's revenue came from those areas of the business, versus just 12% from IB advisory.

But if advisory services were hurting in 2011, trading was even worse. Revenue for market making fell by a third through the first three quarters, while principal transactions revenue plunged 87%. The latter was driven primarily by a disastrous third quarter, when Goldman took a $1 billion hit to its stake in Commercial Bank of China, another $1 billion hit to other equity securities, and close to another billion in its debt portfolio.

And in the midst of all of this, Goldman -- like its competitors -- had to navigate a changing regulatory environment. With regulations aimed at making banks less risky, companies like Goldman that thrive on savvy risk-taking may end up hamstrung.

Still gold in banking?
Goldman Sachs may not have had the best 2011, and it may not be the best financial-industry investment out there right now. But that doesn't mean you should avoid banks in general. In fact, some of the smartest investors have shown interest in the banking sector even as the broad market has shunned the group. But which banks should Foolish investors be sniffing around?
