Online fashion retailer Asos on Wednesday reports its half-year interims following strong second quarter sales.Earlier in March, the retailer impressed with an acceleration in sales growth in the second quarter, but said margins had fallen sharply due to price investments and the roll-out of 'zonal pricing'.It in its half-year interims, analysts are likely to focus on the bottom line.Jefferies said: "The Asos forward fashion offer remains highly differentiated and connects powerfully with the target demographic. The senior management team appears to be back on the front foot operationally and once again, setting the agenda from a communication perspective."The broker predicts a 22% increase in full-year revenue to £1.19bn and an 11% rise in earnings, before interest, tax, depreciation and amortisation (EBITDA) to at £69.1m.Jefferies warned that while Asos enjoyed a "cracking performance" in the second quarter, risks remain amid competition with fellow online fashion retailer Zalando and euro currency headwinds.Wednesday 1 AprilINTERIMSASOSINTERIM DIVIDEND PAYMENT DATEDartyQUARTERLY EX-DIVIDEND DATETorchmark Corp.INTERNATIONAL ECONOMIC ANNOUNCEMENTSAuto Sales (US) (15:00)Construction Spending (US) (15:00)ISM Manufacturing (US) (15:00)ISM Prices Paid (US) (15:00)MBA Mortgage Applications (US) (12:00)PMI Manufacturing (EU) (09:00)PMI Manufacturing (GER) (08:55)FINALSEvrazANNUAL REPORTEvrazAGMSAdvance Developing Markets Fund Ltd.UK ECONOMIC ANNOUNCEMENTSPMI Manufacturing (09:30)FINAL DIVIDEND PAYMENT DATEGeneral Accident (Prf)
