UBS (UBSG.VX) posted on Monday a bigger-than-expected jump in second-quarter net profit as the Swiss bank released results one day early following a newspaper report on the figures. Net profit rose 53 percent on the year to 1.2 billion Swiss francs ($1.25 billion), much more than the 3.2 percent rise forecast in a Reuters poll of analysts that was not published before the Zurich-based bank posted earnings. On Sunday, Swiss weekly Sonntagszeitung said that the Zurich-based bank would post a year-on-year increase of about 25 percent in quarterly net profit.
