Taylor Wimpey is expected to reveal strong sales in the year to date when the housebuilder publishes its trading update on Thursday.Sales in the housing market so far this year have been supported by news of the extension of the Help to Buy scheme. Fellow housebuilder Persimmon last week posted a 7% increase in sales for the first 15 weeks of the new year."We expect a good update from Taylor Wimpey and expect management to report that sales rates since the last update in early March have been strong. We expect the rate of price inflation to have moderated from the near double digit levels witnessed last year, but with build costs also moderating we still think the company will report a small net benefit from price/cost inflation," said Numis analyst Chris Millington.The broker gave the company an 'add' rating and forecast annual earnings per share to rise to 14.3p from 11.1p in the previous year.Gaming giant William Hill also releases a trading update. First quarter earnings are forecast to fall, in part due to weak football betting and an increase in costs.In economic data, a report on UK retail sales will be in focus with analysts predicting a 5.5% year-on-year increase in March. Report on Eurozone manufacturing and US weekly jobless claims are also due.Thursday 23 AprilINTERIM DIVIDEND PAYMENT DATEProduce InvestmentsINTERIM EX-DIVIDEND DATEBarratt Developments, Carr's Group, Edge Performance VCT 'H' Shares, Nimrod Sea Assets Limited, TracsisQUARTERLY EX-DIVIDEND DATEUnileverINTERNATIONAL ECONOMIC ANNOUNCEMENTSContinuing Claims (US) (13:30)Initial Jobless Claims (US) (13:30)New Homes Sales (US) (15:00)GMSRed Emperor Resources NL (DI)FINALSAir PartnerANNUAL REPORTMail.ru Group Ltd GDR (Reg S)IMSSCobham, Computacenter, Taylor WimpeySPECIAL EX-DIVIDEND PAYMENT DATEElementis, Hansteen Holdings, Novae Group, OMGEGMSForesight Solar Fund Limited, Independent News & Media, Urals Energy Public Co Ltd.
