Tottenham chairman Daniel Levy and Matt Mirchin, Senior VP, Global Brand & Sports Marketing of Under Armour, joined players and officials from New York Red Bulls to ring the Closing Bell at the New York Stock Exchange on Tuesday.
The ceremony takes place at 4pm local time and signals the end of the day's trading.
It is a tradition of the New York Stock Exchange going back over 100 years.
It is televised daily in the USA on the 'Closing Bell' programme on CNBC and to an audience of over 150 million worldwide. It was live on CNBC in the UK.
Levy said: "It is a tremendous privilege and honour to ring the Closing Bell at the NYSE. It's an amazing event and we were delighted to share the podium with tonight's hosts the New York Red Bulls and our new technical partners Under Armour. I feel it is a fantastic way to mark the commencement of our partnership with Under Armour as well as round off what has been an extremely rewarding tour of the United States."
