Hello, I'm Gerri Willis and welcome to Rich Is Not A Four Letter Word, the podcast for your wallet. One word to focus on today - volatility. That's what the stock market has been all about and what traders down on Wall Street are talking about. I spoke to one of them on the floor of the New York Stock Exchange, Stephen Guilfoyle, also known as Sarge, about what to make of the extreme ups and downs plaguing the market now.
