Markets edged higher on Tuesday morning as traders reacted to a barrage of corporate earnings and data which showed that German consumers were at their most optimistic in six years.The GfK's forward-looking consumer confidence survey for Germany rose from 6.8 to 7.0 in August, its highest levels since September 2007, as indicators for economic and income expectations as well as willingness to buy all increased in July. The consensus forecast was for a smaller increase to 6.9. The report said: "As summer finally arrived in Germany, it was not just the temperature but also the mood of consumers that was rising this month. The continued stability of employment prospects and a moderate rate of inflation caused optimism to rise once more in July."However, Market Strategist Ishaq Siddiqi from ETX Capital said that "traders in general are hesitant to build too much risk exposure ahead of some key events scheduled this week".The outcome of the Federal Open Market Committee meeting will be in focus on Wednesday, though analysts widely expect the Fed to keep its asset purchase programme unchanged until at least September.
