Aug 27 (Reuters) - London's FTSE 100 retreated on Thursday as earnings updates from firms including Rolls-Royce underlined the extent of the corporate damage from the COVID-19 pandemic ahead of the annual Jackson Hole central bankers' conference later in the day.
The blue-chip FTSE 100 .FTSE fell 0.3%, with banks .FTNMX8350, insurers .FTNMX8530 and energy stocks .FTNMX0530 leading the declines.
Rolls-Royce RR.L tumbled 7.3% to a more than three-week low after sinking to a first-half underlying loss before tax of 3.2 billion pounds ($4.2 billion). The wider aero and defence index .FTNMX2710 lost 1.8%.
All eyes are now on U.S. Federal Reserve Chair Jerome Powell's address at the virtual Jackson Hole Symposium, where he is expected to outline a more flexible approach to policy, including targeting an average inflation rate of around 2% that will allow rates to stay super-low for longer. MKTS/GLOB

Hays Plc HAYS.L, one of the world's biggest recruitment agencies, rose 1% even as it posted a 12% fall in annual net fees, while advertising company WPP WPP.L jumped 4% as it resumed its dividend after beating dire forecasts for second-quarter trading.
