"CEOWORLD magazine's global ranking of the best chief executives for 2019 measured more than 1,200 CEOs across 96 countries. Taking a long view of business performance, the methodology is primarily based on the financial returns for the CEO's entire tenure, which makes up 60 per cent of the final ranking, as opposed to stock price and the current quarter's numbers," the publication said.

To calculate the final position, the additional 40 per cent of a CEO's ranking factors in a company's track record on environmental, governance, and social issues, as well as market shares, change of market capitalisation, and brand's newsworthiness and the impact was taken, it added.
