Wall Street has had a disastrous year

Poor trading results and low client activity in the second half of the year led to an overall drop in revenues for Wall Street banks.

That's according to the data-analytics company Coalition, which just released its annual index of investment bank performance.

They tracked performance in key business divisions at Bank of America Merrill Lynch, Barclays, BNP Paribas, Citi, Credit Suisse, Deutsche Bank, Goldman Sachs, HSBC, JPMorgan, Morgan Stanley, Societe Generale and UBS.

Fixed income divisions disappointed in particular, as corporate bond trading revenues fell more than 30%.

Jobs were lost too, with headcount down around 800.

The bad news for Wall Street is that 2016 looks like it could be even worse. JPMorgan analyst Kian Abouhossein has forecast a 19% drop in fixed income revenues and a 16% drop in equities revenues in 2016 versus 2015.

Here's the breakdown.
