A busier week than last week is in store with FTSE 100 stocks Bunzl, G4S, Admiral, Serco, WPP Group, Cairn Energy, Kazakhmys and Diageo all due to make trading announcements.Distribution and outsource specialist Bunzl gets the show on the road on Monday with its interim results. The company has already indicated that revenues for the first half of the year rose 17% though underlying revenue, which removes acquisitions and exchange rate fluctuations from the picture, was marginally lower. Broker Charles Stanley is expecting a slight improvement in interim pre-tax profits to £117m from £110.8m last year.Security solutions provider G4S is also due to announce figures on Monday. Panmure Gordon believes the focus will be on 'the extent to which the company's organic growth is slowing and the strength of its margins at this stage of the cycle.'The broker is forecasting revenues of £3.2bn versus the £2.7bn seen in the first half of last year. Earnings before interest, tax and amortisation are tipped to rise to £208m from £174.8m while adjusted pre-tax profit is forecast to rise to £173m from £139.8m. That's a little bit more optimistic than Charles Stanley's forecast of profit before tax of £165m. Drinks company Diageo, best known for its Guinness brand, releases full-year results on Thursday, and investors will be looking to see whether the weakening trend in sales reported at the nine-month stage has continued. Charles Stanley expects organic sales to be 0.3% lower year-on-year.
