"You start the trading for the day by ringing the bell at the stock exchange. It was pretty cool.
"They put us up at The Ritz for two nights, and flights and accommodation were paid for."
Mr Etti said the experience of ringing the bell was different than he thought it would be, witnessing a very relaxed environment at the stock exchange.
"I spoke to one guy who had worked there for 30 years, and he said he'd seen a change since being there from like the paper tickets that they used to have. Those crazy times where people would just yell out everywhere, to where it's just fully automated on the computers now," Mr Etti said.
"Looking at all the craziness that was done before, it's quite a subdued environment.
"No one was yelling or stuff like that, and people were just looking at computer screens, they looked quite relaxed."
He added that other highlights of the couple's trip included seeing Jersey Boys on Broadway, visiting the 9/11 Ground Zero site, and "experiencing everything that New York had to offer, from the helpful and friendly people, to all the magnificent buildings and landmarks".
