Low-cost airline easyJet (LSE: EZJ) has had a good year. It carried almost 10% more passengers in 2017 than in 2016. Its load factor (which measures the number of passengers as a proportion of the number of seats available) increased by 1.6 percentage points to 93%. In December, the airline also announced an expansion in Germany by buying part of collapsed carrier Air Berlin's operations at Berlin Tegel Airport.

Advertising giant WPP (LSE: WPP) saw its share price fall by more than 25% in 2017. In the first nine months, WPP's like-for-like revenue fell by 0.9% as huge customers cut marketing budgets after questioning the effectiveness of buying online advertisements through media firms, rather than turning to Google. As a result, WPP cut its forecast for the third time in October and now expects to see flat like-for-like net sales growth for the full year.
