Financial stocks have been brutalized in 2011. Some of the biggest losers on Wall Street in 2011 include Bank of America (NYSE:BAC) and Citigroup (NYSE:C) — and thanks to some moron at UBS AG (NYSE:UBS) losing a cool $2 billion on risky trading, the sector isn’t exactly instilling confidence in investors these days.

I watch more than 5,000 publicly traded companies with my Portfolio Grader tool, ranking companies by a number of fundamental and quantitative measures. And this week, I’m tracking eight big bank stocks that are not instilling confidence in investors.

Here they are, in alphabetical order. Each one of these stocks gets an “F” according to my research, meaning it is a “strong sell.”

Bank of America is a financial stock that serves individual consumers, small and middle market businesses, corporations and governments. Year to date, BAC stock has dropped 52%, compared to a drop of just 4% for the Dow Jones.

Barclays PLC (NYSE:BCS) is a global financial service provider involved with retail banking, credit cards, corporate and investment banking and wealth management. Despite having a $28 billion market cap, BCS stock has slipped 44% since this January.

Citigroup provides consumers, corporations, governments and institutions across the globe with a range of financial products and services. A year-to-date drop of 46% for C stock has left shareholders shaking their heads throughout 2011.

Credit Suisse (NYSE:CS) is known for providing advisory services, solutions and products to companies, institutional clients and private clients globally. CS stock’s yearly performance has been a sore spot for investors, having dropped more than 40%.

Deutsche Bank (NYSE:DB) is a global investment bank that provides investment, financial and related products and services to its varied group of clients. A year-to-date drop of nearly 40% for DB has potential investors running.

Goldman Sachs (NYSE:GS) is known as a bank holding and financial holding company that provides numerous financial services to its clients. GS might be known internationally, but a year-to-date drop of 42% has dragged this bank stock’s name through the mud.

Morgan Stanley (NYSE:MS) is another global financial services firm making this list. MS has been a big loser in 2011, dropping more than 49% in less than 10 months.

UBS AG is the financial services company made infamous for having lost $2 billion recently for less-than-stellar trading practices. Additionally, a year-to-date performance of 33% for UBS has shareholders jumping ship.
