Tullow Oil, Unilever and Marks & Spencer were at the top of the FTSE 100 game on Wednesday.Tullow Oil led the race, a day after the company said it completed the acquisition of Spring Energy Norway AS. The group announced that the acquisition had already brought success for Tullow. Also to be had in account, its shares bounced off of technical support at 1,150p. Nipping at its heels was Unilever which advanced after the consumer products maker beat sales forecasts. The Anglo-Dutch giant said it exceeded €50bn in annual turnover for the first time, driven by growth in emerging markets. Coming in at third place was Marks & Spencer amid rumours of a takeover bid following bleak sales updates. Topping the list of fallers was Europe's largest tour operator, TUI Travel, which made headlines after its German parent company TUI AG decided against a merger with the group. Energy giant SSE followed close behind after announcing Chief Executive Ian Marchant would step down after 10 years in the role. The stock also went ex-dividend today.Lastly, Compass Group, also ex-div today, dropped following recent damning comments from Portuguese investment bank Espirito Santo which said the company will lose its direction in 2013.FTSE 100 - RisersTullow Oil (TLW) 1,192.00p +3.20%Unilever (ULVR) 2,522.00p +2.90%Marks & Spencer Group (MKS) 377.70p +2.16%Petrofac Ltd.
