The share price of SIG, the supplier of construction products, has been slowly picking itself up off the floor after the company's profit warning in June and tomorrow's interim results should show whether the recovery has been justified.The group said on 18 June that volumes had remained subdued across all businesses in the UK, while European markets had not achieved the usual level of seasonal improvement in the last four weeks. The situation had not changed by the time of its 10 July trading update, though at least that meant trading conditions had stabilised.Attention is likely to focus on current trading and the company's cost reduction programme. Sensor and electronic components firm TT Electronics said at the end of June it had traded profitably in May and June as the company's cost reduction programme began to bite - the implication being that the first four months of the year had not been profitable. On the bright side, net debt at the end of June is likely to show an improvement on the position at the end of 2008.INTERIMS1st Dental Laboratories, Cineworld Group, IP Group, ProStrakan, SIG, Spirax-Sarco Engineering, TT Electronics, Wellstream HoldingsQUARTERLY PAYMENT DATECaterpillarINTERNATIONAL ECONOMIC ANNOUNCEMENTSInitial Jobless Claims (US) (15:00)Leading Indicators (US) (15:00)Philadelphia Fed Index (US) (15:00)Convenience Store Sales (JPN)FINALSVantisAGMSAlbany Inv Trust, City of London PR, Latham (James), Summit CorporationUK ECONOMIC ANNOUNCEMENTSPublic Sector Finances (09:30)Retail Sales (09:30)Money Supply (09:30)FINAL DIVIDEND PAYMENT DATEAshley (Laura) Holding
