Seven of the UK’s 10 biggest blue chip companies report in the coming week, plus four of the five big banks and, across the Atlantic, tech titans including Apple and Alphabet.

With these FTSE 100 giants spread across the global pharma, commodities and consumer goods industries, it is likely to provide a crucial litmus test for the health of the global economy and the direction for equity markets for the coming weeks.

With some Wall Street watchers worrying about a bubble as earnings season rolls round to include two of the world’s largest companies and a Federal Reserve policy statement, it’s undoubtedly a compelling week for finance fans.

There should be no confusing what the key focus of Plc’s () upcoming update – it’s all about the dividend.

Shell shocked the market in April as it cut its dividend for the first time in eight decades, leading it to lose its crown as the most highly valued company in London.
