Report That ECB May Curtail Emergency Aid to Greek Lenders Alarms Investors

In Paris Publicis (PUB) gains posting strong first-quarter revenue growth, including an unexpected increase in “organic” sales. In London pay-TV company Sky and ARM lead the FTSE 100 gainers, with the chipmaker suggesting it may exceed dollar-denominated revenue forecasts this year. But Associated British Foods sours after the sugar producer and discount clothing retailer says the euro’s weakness will bite into earnings this year and next.
