Coca Cola Enterprises (CCE) shot higher on Friday on reports the company is in merger talks with two European bottlers of the soda products.

Stocks were volatile on the final day of trading for July as the energy sector pressured markets. Crude oil was on track for its worst month of the year after falling around 20% over the period.

Exxon reported its lowest profit since 2009 and Chevron generated sales one-third lower than a year earlier. Both have been hit hard by the challenge of lower oil prices.
