Inside the Wall Street charity day where celebrities and star athletes pretend to be traders

Trading firm BTIG held its 14th annual Commissions for Charity day on Tuesday, and a slew of celebrities flocked to the trading floors.

The baseball player Alex Rodriguez, model Petra Nemcova, basketball star Shaquille O'Neal, and some 70 other A-listers spent the day as "guest traders," taking calls from clients.

BTIG's cofounder, Steven Starker, was there chatting with all the celebrities too.

Commissions from the trades BTIG made were donated to various charities.
