There’s a great story about a famous local trader at the Chicago Board of Trade (CBOT). One day, he was on the floor of the CBOT and a U.S. inflation number came out that was totally unexpected. Pure pandemonium ensued. When all the noise died down, he walked out of the pit having made $10 million and said, “By the way, what was the number?”
