Cristian Ronaldo, Coca-Cola and four other times people in the public eye have influenced the stock market

Celebrities have a long reach when it comes to endorsing or criticising a product 

Ronaldo appeared to snub Coca-Cola 

On Monday, footballer Cristian Ronaldo effected a major change on the global value of a global brand when he moved two bottles of Coca-Cola away from him during a press conference for Euros 2020 in Budapest. Holding up a bottle of water and saying "agua" - Portuguese for water - Ronaldo appeared to be urging us to drink it instead. 

Coca-Cola's share price dipped almost immediately by $4bn, promoting the international drinks company to respond with a statement saying “everyone is entitled to their drink preferences”.
