2006: Before the financial crisis of 2008, Wealth Management and Trading Revenues contributed equally (around 35%) to UBS's total revenues.
2010: WM's contribution increased to about 40% with Trading revenues accounting for 30% of total revenues.
2014: Since 2012, UBS significantly reduced trading operations and increased its focus on wealth management business. As evident from 2014 numbers, UBS was largely successful in overhauling its business model, with WM's contribution increasing to 53% while trading revenues were reduced to a mere 18%.
2018: Wealth management now accounts for more than 55% of UBS's total revenues while Trading division's contribution has remained stable around 18%.
Trefis projects this contribution to remain stable around 55% over the next few years.
