- Markets give mixed reaction to corporate earnings- Ukraine tensions continue to rise- Investors nervous ahead of Yellen speechtechMARK 2,783.30 -0.31%FTSE 100 6,773.54 -0.37%FTSE 250 15,890.46 -0.30%A flurry of mixed corporate earnings pushed UK markets lower on Wednesday morning, while investors scaled back risk in the face of heightened tensions in Eastern Europe.Experian, CRH, Sainsbury and HSBC were all trading lower after reporting results, while Legal & General, G4S and Imperial Tobacco headed higher on their numbers.The FTSE 100, which hit a two-month high of 6,822.42 on Friday, was in negative territory for a second straight day, trading down 0.4% at 6,774 by midday.As fighting continues across cities in eastern Ukraine, pro-Russian separatists in the region of Donbass said they would hold a referendum on secession on Sunday May 11th. The US has warned that any such attempt would be illegal and further sanctions would be applied on Russia if it went ahead.Meanwhile, a top ranking official at the OSCE has called for a ceasefire in Ukraine so that "fair and inclusive" elections can be held on May 25th."The troubles are dreadful," said analyst Holger Schmieding from Berenberg. "But so far, they remain below the threshold of an open Russian invasion (Russian tanks rolling West) that could cause a huge rather than just a modest negative confidence shock across central and western Europe and derail the European recovery."Injecting further caution into markets was anticipation of a speech by Federal Reserve Chair Janet Yellen later this afternoon as she testifies before the Joint Economic Committee of the US Congress.For now at least, markets have generally come to believe that the US central bank is in no hurry to initiate rate hikes. However, given the debate about how inflation will act as the labour market continues to recover, her words are likely to be watched very closely. Fallers: Experian, CRH, Sainsbury, HSBCExperian disappointed with its outlook statement as it said it faces "a number of one-off headwinds" that will constrain growth in the first half.
